Using Your E-500

My other articles related to the Olympus E-System cameras.

These are some explanations and recommendations on using the Olympus E-500 digital camera. It is a companion to another piece, Customizing Your E-510, E-410, or E-500, which I would recommend reading before (rather than after) this one.

Two topics have been excluded from this article: flash photography and image reviewing functions. I am considering separate articles on these subjects, at least on the latter.

I am also planning to extend this piece so that it becomes fully applicable to the new E-510; at this moment you just have to assume that most of the information here is applicable to that camera, although the new features (most notably: Live View and Image Stabilization), obviously, are missing.

There is also a French translation PDF file available.

Table of Contents

This is a rather long article, so I think you may find this table handy in navigating it.

Why bother?

Yes, you can set your E-500 to AUTO and just keep pressing the release button. But if you wanted to rely on this, you would have bought a point-and-shoot camera with a super zoom, fifty scene modes, movie feature, and an MP3 player thrown in.

But no, you wanted creative control; that's why you bought an SLR. You believe that an intelligent human being is capable of making better decisions than a computer program. You want to take your pictures, not to let the camera take them. And, yes, you are right!

A remark on terminology: the term point-and-shoot refers to cameras allowing the user no control over the picture-taking process except for framing, zooming, and choosing the moment the picture is taken: just point and shoot. More specifically, I'm talking here about the user setting exposure parameters; this is where I would draw the line. Different "scene modes" do not count: the user still does not know what the camera may change and why.

I have seen this term used, sometimes disparagingly, for any non-SLR camera. This only shows illiteracy of the writer; the term is well-established. It is difficult to classify a Graflex or Leica as a P/S, while some consumer SLRs of the past were darned close to P/S, offering only program modes with no override capabilities.

Classifying a camera as a point-and-shoot has nothing to do with the format, viewing system, or lens interchangeability. It is all about control, or the lack of it.

Actually, most SLRs can emulate a P/S camera when set to an "All Auto" mode, and many P/S models allow for some limited exposure adjustment (like compensation). The borderline may be a bit fuzzy.

Adjustable parameters

All settings available in cameras can be roughly divided into two groups:

  • User preferences, customizing the camera to your liking and working habits. These, once set, will be rarely, if ever, modified, as this only multiplies the number of variables you have to remember about, check, and/or control, making the picture-taking process more convoluted and error-prone.

    Examples: ISO adjustment step; functionality of the Lock button.

  • Shooting parameters, adjusting the camera's behavior for the current picture (or group of pictures); these may be changed often, sometimes even for every frame.

    Examples: exposure mode, exposure compensation, white balance, ISO, drive mode.

While the dividing line between these groups is not always clear, most parameters, like the ones shown as examples above, leave no doubt.

The first group (user preferences) is discussed in another article. Here we focus on the second one: shooting parameters.

External controls

All external controls of the E-500 (buttons, switches, and dials) are located on the camera's back and top. Here they are, at a glance:

The camera top houses some of the essential controls:

  • The On/Off switch;
  • The shutter release. In addition to the basic functionality of causing a picture to be taken, the release, when half-pressed, locks the autoexposure (AE) and/or autofocus (AF). It can be used in conjunction with the AE/AF lock button, and the way both co-operate is widely adjustable to your preferences.
  • The Mode Dial, used to switch between different exposure modes, discussed below;
  • The exposure compensation button. Pressing it allows for the proper exposure adjustment to be dialed-in using...
  • The control dial. This is the most essential part of the camera's user interface, and it can be used in four (!) different ways:
    • Most of the externally accessible adjustments are performed by pressing a dedicated button and turning this dial while the camera is in the shooting (as opposed to image review) mode.
    • When the Control Panel is used to select a given setting, the dial is used by itself to modify that setting.
    • Without any button pressed, the control dial can be used for
    • When the camera is in image review mode, turning this dial changes the magnification of the viewed picture.

The part of the camera back to the right of the LCD monitor houses quite a number of control buttons:

  • The AE/AF lock, see below how it works, and in my settings article how to customize it.
  • The Reference WB button. Releasing the shutter while this button is depressed (and the camera pointed at a neutral surface) performs the scene white balance measurement, a very precise way to get the WB right. This is described in a separate section.

    It is quite easy, depending on the way you usually hold the camera, to have your thumb hold this button down by accident when attempting to take a picture. This leads to one picture being lost (WB measurement taken instead!), and the white balance in all following frames being set to the result of that measurement — most probably wrong, unless you were shooting a white (or gray) area. This is due to a design error: the indentation on top of which this button is located is not large enough (it is OK in the E-300, and the problem does not occur on that camera). There are three ways to avoid this danger:

    • Developing a habit to check the WB setting in the monitor at every opportunity, or at least from time to time (checking the settings often is a good idea anyway).
    • Swapping the functionality of the Reference WB and AE/AL buttons (available only with firmware version 1.2 or higher). This is a half-measure, as now you may be activating the lock by accident.
    • Disabling this button altogether (firmware 1.2 or higher). This is OK only if you never set the white balance by reference, and it means giving up this, sometimes very useful, function.

    A friend of mine used to experience this problem quite often, until I looked at the EXIF information in her pictures and figured out the reason. It also happened to me, twice on the same day in a hot, Caribbean weather — with sweaty palms I tend to hold the camera it a different way than usual. Still, this was just one day out of ten months of using the camera, and I decided to keep the button functionality unchanged. Your pick.

  • AF spot selection: press and turn the control dial. The function is described further down this page.
  • Drive mode; this includes also self-timer and infrared remote; see the detailed description.
  • The four arrow buttons to the right of the monitor, arranged in a circular pattern, have dual functionality. They are used for navigation when the menu is displayed, Control Panel active (not just shown), or in the image preview mode; otherwise they have separate functions assigned as marked, used in conjunction with the control dial (press and turn): white balance, metering pattern, focusing mode (marked as [AF]), and ISO setting.
  • The [OK] button in the center of the arrow cluster is used to confirm menu choices (if the menu is active), or to switch the Control Panel (if displayed) into the active mode. Once the panel is in the active mode, the [OK] button will bring in the dedicated adjustment screen for the selected (highlighted) setting. Just have a look how it works, to save me a more detailed (and possibly cumbersome) description.

The buttons to the left of the LCD monitor are, except for the round flash mode button, dedicated to monitor and image review functions.

  • Image review (green arrow): toggle between shooting mode and image review mode;
  • Delete image (red trash can): delete the currently viewed image from the memory card. Not active in the shooting mode.
  • Menu on/off, marked as [MENU]: Toggle the menu system.
  • Control Panel on/off, marked as [INFO]: in the shooting mode toggles between three states of the Control panel: simple, detailed, and off; in the image review mode changes the amount of information overlaid on the displayed image.

The round flash mode button, just above these four, serves a dual function:

  • When the built-in flash is in the "down" position (and no external dedicated unit mounted and powered), it will be raised, and the camera will start charging it;
  • With either flash powered, pressing this button and rotating the Control Dial will switch between various flash modes.

Note also the diopter adjustment knob, immediately to the left of the viewfinder eyepiece. Surprise: this one is purely mechanical!

Using the external control buttons

All external control buttons are used in one of two ways:

  • By itself: pressing a button activates (or toggles) a state: this applies to the image review, delete, Menu, and Info (Control Panel) buttons (all to the left of the LCD monitor), and also to AEL/AFL lock and custom white balance buttons.
  • Together with the control dial: pressing a button brings a dedicated adjustment screen to the monitor (switching it on, if necessary); then the adjustment is done by turning the control dial. This is how all other buttons work.

(The flash button is a mixed case, as described above.)

If the control dial is not moved within a short time period after pressing the button, the adjustment screen goes away. This "grace period" can be adjusted to your liking.

While the press-and-turn method is the fastest way of making an adjustment, not all functions are accessible this way. Many of those which are not (in addition to those which are) can be accessed from the Control Panel, discussed in the next section.

The Control Panel

There is nothing wrong with accessing the preference parameters through the menu system, very much like the custom functions in some film SLRs ("set the custom function 5 to setting number 3"). You do it just once.

The shooting parameters, though, should be accessible more easily, without scrolling through a menu just to find them. At least this should be the case in a well-designed camera.

Ideally, every shooting parameter should be serviced with its dedicated dial, with the dial position showing at a glance the parameter's setting. This is right: the same interface element is used to adjust the setting and to see its current value. This is how it used to be in all classic SLRs.

Digital cameras are facing a problem here. First, the number of adjustable parameters is higher than in film cameras, adding variables which were not directly controllable there, like the ISO setting (before: load another film) or color balance (ditto, or put a filter on). Secondly, the manufacturers strive to lower production costs, if only to offset high R&D and prototyping expenses they are incurring while the technology is still evolving fast. Extra buttons and (especially) dials cost more than electronics does, and they take extra room on the camera body. This is why digital cameras are, generally at least, not as obvious, easy, and pleasurable in operation as the classic film ones.

In spite of those limitations, the designers of the E-500 did an exemplary job, much better than that on any other camera, except maybe the Minolta Maxxum 7D. The camera differs from all previous Olympus models. First, it inherits from older models two control metaphors:

  • For the most frequently adjusted parameters: press a button and turn the control wheel, seeing a feedback on the monitor.
  • For others: find the right option in the menu, use cursor keys to adjust it.

Second, it adds a new way of doing things, and this may be the most under-advertised feature of the camera:

  • Use arrow keys to find the right option on the Control Panel (CP), then turn the wheel to adjust it.

This may sound like much, but in real life it is almost revolutionary. Sometimes I find it faster to use the CP than a dedicated button, and I usually have a look at the CP anyway, to see all parameters at a glance.

Actually, there are two versions of the Control Panel: brief and full; they are toggled with the [INFO] button at the bottom left of the camera's back; the third state is, obviously, Off.

In the beginning, right after I bought the E-500, I tended to use the full version more; now, when I'm no longer tweaking the camera, and when my essential preference setup is rather stable, I find the brief version more intuitive in use: if a given setting is not shown there, this means it rather should not be adjusted during a shooting session.

Individual settings

Let me go through individual settings and adjustments, starting from those which, I believe, may be used most often.

Before that, however, let me describe the procedure of adjusting a setting from the Control Panel; I will be referring to that procedure all over the place.

  • If the Control panel is not on, activate it by pressing the [OK] button;
  • Use the arrow keys to select (highlight) the setting you need to modify;
  • Use the control wheel to scroll to the desired value (choice) of that setting;
  • If you want to modify another setting, go to (2) above; otherwise press the [INFO] button (possibly twice) to turn the Control Panel off.

Before turning the Control Panel off, it is a good habit to verify that the remaining settings are what you want. Forgetting to do that is one of the main reasons of botched pictures.

Raw or RGB?

The Control Panel allows you to save images raw (.ORF files, containing the original information as taken off the sensor), as TIFF files (converted to RGB, no compression), or in the common JPEG format (converted to RGB, compressed). For more about this, see a separate article in the Nitty-Gritty section.)

While this choice should be rather made at the stage of customizing the camera, not being changed from one shot to another, it will affect a number of shooting adjustments discussed further down.

Some of the camera settings do not affect the picture-taking process (i.e., the exposure proper), but are applied only at the stage or raw-to-RGB (TIFF or JPEG) conversion; therefore if you are shooting raw, they will not be really relevant; the decisions are being postponed until the raw development stage in postprocessing on your computer.

Even if not applied, these settings are still stored as metadata in your raw ORF files; during the off-camera conversion you may apply them as set, or use other values.

In particular, these settings are: white balance, sharpness, contrast, saturation, and tonality (high/low/normal key), including any implicit offsets specific to the selected Picture Mode.

The E-500 has also an option to perform the raw-to-RGB conversion in-camera at any time after the raw image has been saved. In such case, the conversion parameters used will be as set when the conversion is done, not as when the picture was taken. Note that the original is retained after the operation.

RGB image quality (size and compression)

This section is relevant only if you decide to save your images as JPEG files. Even then, I would rather suggest not to change the JPEG settings from one frame to another: this is too much hassle, leaving too much chance for an error.

The JPEG format offers three presets, referred to as SHQ (Super-High Quality), HQ (High Quality), and SQ (Standard Quality). The compression can be user-defined for the HQ and SQ formats, and for the latter you can also define the image size in pixels. The options are listed and discussed in another article.

The Control Panel allows for quick switching between RAW, TIFF, SHQ, HQ, and SQ settings/presets. I find the HQ preset as defined in the above article OK for most of my uses, and rarely switch to SHQ, only occasionally using the raw ORF format (which may have some advantages if you really know what you are doing when post-converting your images into one of RGB formats).

Additional options: RAW+SHQ, RAW+HQ, and RAW+SQ, allow for saving, along with the raw, non-converted, version, a JPEG one in a selected sub-format. Unless you are a busy pro, having to send one copy off to your editor while keeping the full-information original for postprocessing later, I doubt you'll find much use for this feature.

Exposure modes

Before we go into detailed settings, we have to discuss the most basic one: exposure mode. This can be changed in only one way: by turning the mode dial, located prominently on the camera top. (Readers familiar with exposure modes may want to skip the remainder of this, rather long, section.)

The exposure mode dial has a number of indented and marked positions, each linked to a particular way in which the camera will be setting the basic parameters: shutter speed and aperture (in some cases, a few others).

The Auto mode

Shown on the dial as [Auto], this is basically a program exposure mode (see below), with all adjustments still enabled. It differs from the Program mode in one aspect only: switching to Auto resets most of the exposure settings to defaults. (The settings will not be lost, though: switching back to any other mode will restore them as they were.)

The parameters being reset to defaults are:

  • Exposure compensation;
  • ISO (sensor gain);
  • White balance (and its adjustments);
  • Picture Mode (the choice between Vivid, Natural, Muted, monochrome);
  • Gradation (normal, high- or low-key);
  • Metering pattern;
  • Drive mode;
  • Flash use (auto, on, off, etc.)

The flash will also rise by itself when needed in the Auto (only!) mode if the Auto Pop Up option in the Settings 1 menu has been activated.

All other settings, which can be rather treated as camera customization preferences, are not affected by switching to the Auto mode. (This includes the image parameters assigned to each of the Picture Modes.)

While this arrangement makes sense, some may find the approach somewhat confusing. I would recommend using the Auto mode only as a "panic button" in a hurry, when you have modified a large number of settings, and need to revert quickly to something reasonably safe.

In my six months with the E-500 I haven't used the Auto mode once, except of playing with it in the very beginning, and again now, to make sure the information in this article is correct.

Program autoexposure

This setting is shown on the dial as [P]. Here things become more predictable. In the program exposure mode the camera sets both shutter speed and aperture, with all other settings adjustable and remembered between mode switching. This is how most of us will use the camera.

The exposure program in the E-500 is quite straightforward, at least at a given (non-Auto) ISO setting. Going from low to high light levels, the procedure is as follows.

  • In the low light the lens stays wide open (maximum aperture, or smallest F-number) and the shutter speed is adjusted as needed.
  • When the shutter speed reaches a pre-defined value (see below), the camera will start closing down the aperture while still making the shutter faster: for every 2 EV in light increase, the shutter will be sped up by one EV (i.e., doubled), and the aperture will be closed down by one F-stop (which also corresponds to a factor of 2 in exposure).
  • This continues until the F-number reaches a pre-defined value (see, again, below); then the F-number increase stops and only shutter speed increases, until the fastest value is reached.
  • When no further shutter speed increase is possible, the aperture starts closing again, up to the maximum F-number (which, on most Four Thirds lenses, is F/22). Proper exposure is impossible beyond that point (EV 21).

Judging from the exposure graphs provided by Olympus, the shutter speed when the camera starts adjusting both exposure parameters depends on the lens focal length (in case of a zoom, the one currently set), and is set to be one over doubled focal length; for example, for 50 mm it will be 1/100 of a second. This is consistent with the blur-prevention rule of thumb used with 35-mm cameras for the same image angle.

(If you would like, you may skip over the detailed discussion of the program exposure. I won't be offended, and you will save a few minutes...)

In most of film cameras, the pre-defined F-number used in phase (3) is the maximum value possible for the given lens, so that phase (4) is absent. In the E-System, though, this value has been chosen as F/11. The reason is diffraction: loss of sharpness at smallest aperture openings. The effect depends not on the relative F-stop value, but on the absolute diameter of the lens aperture (measured, say, in millimeters), and this is smaller for cameras with smaller sensors. It is, therefore, preferable to start closing the aperture beyond F/11 only when we run out of fast shutter speeds.

The diffraction-limited aperture value may depend on the focal length used (being higher for longer lenses), but the three program curves published by Olympus, for focal lengths ranging from 14 to 54 mm, all bend at F/11.

Strangely, the E-300 and E-500 manuals do not include program exposure graphs for the lenses bundled with these cameras, only for the 14-54 mm zoom and 50 mm macro. It is possible that the program selects higher limiting F-stop for longer lenses, but I haven't checked that.

Here are the Olympus program curves I have derived based on the above information, for the two E-500 kit lenses.

  • 14-45 mm, F/3.5-5.6
    •    Green: at F = 14 mm
    •    Blue: at F = 45 mm
  • 40-150 mm, F/3.5-4.5
    •    Yellow: at F = 40 mm
    •    Fuchsia: at F = 150 mm

The diagonal lines denote EV exposure indices (read: scene brightness): all points on a given line have the same exposure.

For example: at EV 16, with the 14-45 mm zoom the program will set 1/500 s at F/11 (regardless of the focal length set), while with the 40-150 mm lens at 150 mm it will use 1/1000 s at F/8.

If you understood the verbal description in points (1..4) above, the picture is redundant; you can ignore it and live happily ever after.

If ISO is set to Auto, then at the lowest light levels (with the lens fully open) we could expect the program to raise the ISO setting. Not so: the ISO stays at 100 all the time, and the auto-increase is applied only when shooting with flash.

Program shift

The basic autoexposure program, as described above, can also be shifted towards faster or slower shutter speeds. This corresponds to moving the exposure-versus-shutter line described above to the left or to the right. For example, if the regular program comes up with the exposure of 1/60 s at F/8, shifting it by 1 EV towards faster shutter speeds will result in 1/125 s at F/5.6 — this is the same exposure (amount of light on the sensor), achieved with a different parameter combination. Shifting the same exposure by 1 EV towards slower shutters will give 1/30 s at F/11.

While some users will find the program shift useful in controlling the depth of field and/or motion blur, the same effect can be achieved just by using aperture priority (or shutter priority) mode. I could easily live without it, but with the market increasingly driven by feature count (or, to use Ken Rockwell's term, measurebators), makers would not dare not to offer it on their models.

Shifting the program is done by turning the control dial when the AE system is active (for some time after the shutter release has been half-pressed, or after the picture has been taken); turning the wheel to the right increases shutter speeds. The exposure mode indicator, both in the viewfinder and Control Panel, changes then from "P" to "Ps". It it, unfortunately, too easy to move the wheel by accident and apply the shift without being aware of it. Therefore it is a good habit to check for the "Ps" mark before every picture and remove the shift if it has been dialed in by accident.

This may be not so simple as it sounds, as the indicator does not show in which direction the program has been shifted. You may end up dialing even more of a shift when trying to remove it, and the only indicator will be the disappearance of the small "s". It may be faster just to move the mode dial off the Program setting and then back. An arrow icon instead of the ambiguous "s" would be a better indicator.

Aperture priority

In this mode, shown as [A], you set the aperture (by turning the input dial) and the automation system adjusts the shutter speed to provide proper exposure. While this mode of work is most useful when you want to have some explicit control over the depth of field, many photographers use it all the time.

Usually you will be in one of two situations.

  • One is when you want to get as shallow DOF as possible, to isolate the main subject from the background (for example, in portrait photography). To do that, you will use the widest aperture (smallest F-number).

    This effect is also easier to achieve at longer focal lengths, when the DOF is smaller, but even so, most of the zoom lenses, with not-too-large apertures, may provide more DOF than you would wish. That's why large-aperture lenses (usually of fixed focal length) are often chosen for this kind of work.

    In particular, the 50 mm, F/2 ZD lens from Olympus is a very nice option for portraits, with the focal length (equivalent to 100 mm on a 35-mm film camera) being ideal for head-and-shoulder or face close-ups, and the large aperture providing shallow DOF. Another alternative (announced although still not available) is the 30 mm, F/1.4 lens from Sigma, impatiently awaited by many Four Thirds photographers.

  • The opposite situation is where you want to maximize the DOF (for example, in tabletop photography). To do that, you step the lens down significantly, at the expense of longer shutter speeds; that's why usually a tripod is used for those applications. In landscapes you may also want to increase the DOF, if only to avoid blurred foreground.

    Stepping the lens down all the way is not always a good idea. While most lenses for the E-500 offer apertures closing to F/22, I would recommend against using values beyond F/11 (or even F/8 with shorter lenses), unless you are willing to accept some unsharpness as a price for more DOF. The reasons are discussed in the section on program exposure.

    If you are reading a review of a camera with a 1/1.8" or smaller sensor, and see complaints why the makers allow to close the lens only down to F/8 or F/11 but not higher, be warned: the writer is simply unaware that there are some laws of physics you have to live with.

Actually, a camera with just aperture priority, and no other exposure modes, would be as usable as one with all different AE modes and dozens of "scene" ones, except that it would be trashed in all reviews, so no manufacturer dares to think about such a model.

The last set aperture value is remembered next time you enter the aperture priority mode again.

Shutter priority

To use the shutter priority, set the mode dial to [S]. Now you will be setting the shutter speed, and the camera adjusts the aperture in order to provide the right exposure. This mode can be used to assure that motion blur is avoided (or, to the contrary, introduced on purpose),

As the aperture range extends for just a few EV units (F-stops), the system may easily run out of the adjustment range; this will be shown with the aperture value blinking in the Control Panel and inside the finder. In such case the image will be under- or overexposed, unless you switch to a different shutter speed. If not, the picture will still be taken, improperly exposed as it is.

There are two other kinds of behavior possible in such cases: one is just refusing to release the shutter, another, to use the largest or smallest aperture available, and then adjust the shutter as needed to still provide the proper exposure. I believe the second approach works best, and I think Olympus should have used it.

The last set shutter speed will be remembered next time you enter the shutter priority mode again.

Manual exposure

Turn the dial to [M] and the camera will not set either aperture or shutter speed; you are on your own. This is useful in some non-typical situations (like, for example, taking pictures of effects made by moving light sources). I also switch to manual always when shooting the Moon. In short: there are situations when you know better what exposure to use.

Not only: with a non-dedicated, auto-thyristor flash you will be setting the shutter to a speed of, say, 1/125 s, the aperture to a value your flash expects, and then the flash will be adjusting its output according to the readings of its own sensor. While this is not exactly a manual exposure (the flash is doing the metering), your camera does not know about it. Until I bought the FL-36 flash, I was using the older FL-40 (which does not communicate with the E-500) in this mode, with very good results and no hassle.

While in the manual mode you adjust the aperture with the input dial (thumbwheel); the same dial will adjust the shutter speed if the exposure compensation button is held depressed.

The metering system is still working in the manual mode (that's why it is often referred to as "metered manual"), and the difference between your exposure as set, and the one metered, in EV, is shown in the top-right corner of the Control Panel. For example, "-2.3" means that your exposure is 2.3 EV lower than metered. The same information is additionally conveyed on the exposure compensation scale to the heft of the value shown.

The shutter and aperture used are remembered when you leave the manual exposure mode, and recalled back when you re-enter it next time.

Scene modes

These are pre-packaged sets of settings, supposed to provide good results in particular shooting situations. The approach has its advantages on the mass market, where most camera users never bothered to read a single book on photography.

The E-500 includes five such presets (portrait, landscape, close-up, sports, and night scene) accessible directly from the mode dial, and fifteen (!) selectable from the monitor after the dial is set to [SCENE]. The latter option also includes the five accessible from the dial, but they differ in the degree of adjustments the photographer is allowed to introduce.

  • When the mode dial is in the [Scene] position, you cannot adjust any settings from the Control Panel (pressing [OK] brings you into the screen from which you can switch between different scene modes). From the external buttons, only two are still functional: drive mode and AF point choice. And then you can use the menus to switch between image quality presets and card selection. That's it; quite restrictive, but with a reason: if you are using the [Scene] setting, you should not be trusted to change any settings, period.

    Interestingly, some settings in the Control Panel are then shown in blue. A good guess is that these are the ones specific to the given scene mode, if different from defaults. You may use this feature to get a quick glimpse of what the designers consider "reasonable" for a given application.

    Two of the changes allowed: image quality preset and storage card choice, are persistent: they stay put when you switch between various modes, scene or not.

  • The situation is different for the five presets accessible directly from the dial: they rather reset the camera to a scene-specific setup, then allowing you to change all parameters at will. When you leave the selected preset, all changes (except for image quality and card choice) are lost; this is why you may treat these five as "specialized panic modes".

Unfortunately, there is no detailed information provided on how exactly do the "scene modes" work, even if some information on parameters used is shown in the Control Panel.

If you experiment with some of these modes and find they provide results you like, fine. Still, I would rather recommend that you make the decisions, unless you want to use the E-500 as a point-and-shoot camera, in which case buying it might have been a misunderstanding.

Exposure compensation

This is, no doubt, the setting you will be adjusting most often; possibly for every frame. The reason is that, as much as camera makers try, the autoexposure system will never be sure how do you want your picture exposed. There are many reasons for that, enough for a long, separate, article; let me just use one example.

Take, under identical lighting conditions, close-up pictures of two flowers: bright and dark. The first will be probably underexposed, the other — overexposed, as the camera will use different exposures in both cases, being unable to tell how much of the overall metered scene brightness is due to the ambient light, and how much to the subject itself. You may be using the best super-duper, 1024-point, fuzzy-logic, whatever, metering system, and the camera simply still does not have a way to tell those two factors apart. The exposures as metered will be different, while they should stay identical: after all, the light did not change.

A thinking photographer will use some amount of positive exposure compensation for the first shot, and of negative — for the second. Or, a hand-held exposure meter could be used to measure the incident light, not the light reflected from the subject.

Exposure compensation is implemented in the E-500 in a simple (and quite standard) way: press the button and turn the control wheel to get the desired value, with the Control Panel providing the necessary visual feedback.

See also the section on flash exposure compensation.

Sensor gain (ISO value)

Don't even think about using the menu system to adjust your ISO setting. Instead, do it from the Control Panel, as described in the Individual Settings section, or with the dedicated button (down-arrow).

Adjusting this value up from the default (lowest) ISO 100 is like loading faster film into your film camera. You can use faster shutter speeds and/or smaller apertures (larger F-numbers) at the expense of some increase in noise (in film: grain) and narrowing the dynamic range (maximum highlight-to-shadow ratio the image will convey).

The E-500 images at ISO 200 are difficult to tell apart from those at ISO 100; at ISO 400 they are also respectable, noise-wise. You will get usable results at ISO 800, and quite noisy ones at ISO 1600 (well, for a digital SLR, that is).

Most times outdoors ISO 100 is recommended, as offering the best tonal range. For reasons described elsewhere, I'm not fond of leaving the ISO setting in the Auto position.

Switch to higher ISO if the shutter speed becomes no longer handholdable, and you cannot use a tripod or another form of support. As a rule of thumb, to get the longest "safe" shutter speed, double the (actual) focal length (millimeters) at which you are shooting, and use that as a denominator of the fraction, expressed in seconds.

For example: when shooting with the zoom lens at 45 mm, the safe speed will be 1/90 s.

Remember that this strongly depends on the photographer. Some people press the shutter release with a convulsive jerk; they should use even faster speeds (or learn how to use a camera); some people can shoot handheld at times ten times longer. It may take some practicing, but is less expensive than buying an image-stabilized lens.

White balance

While this setting can be modified directly by pressing its semi-dedicated button (also serving as the up-arrow) and turning the wheel, I found myself, more often than not, adjusting it from the Control Panel. This is because I have this habit of using the panel anyway to quickly verify all my settings. In any case I see no reason why would someone use the menu system to do it.

All digital cameras allow you to set this to Auto. This is rarely a good thing: the WB metering is prone to the same kind of errors as exposure metering. The camera has really a tough time trying to decide if your picture is reddish because your subject is reddish, or because you are shooting under reddish light. (An additional, external WB sensor, which the E-500 does not have, makes it a bit better, but still.) Having a significant white area in your frame may help some, but not quite.

This is why some time ago I switched to using the presets. The discussion which follows is divided, for better readability, into outdoors and indoors sections.

White balance outdoors

When shooting outdoors, most often I'm using the Sunny (5300 K) preset, shown with a sun icon. Actually, the only time I feel a need to change it is the open shade.

The other daylight presets, Cloudy and Open Shade may also be useful: the former when the sky is really overcast, and the latter when you are shooting in clear weather, but screened off direct sunlight (this is the bluest daylight you get). But even if you stick to Sunny in all kinds of weather, you will be probably better off than if you let the camera to do the adjustment.

You have to remember to switch to a different setting when taking pictures indoors without a flash.

White balance indoors

When shooting indoors with flash, leaving the white balance at 5300K should be just fine, but so would be also setting it to Auto. Only when we want to use the ambient (non-flash) light, things are becoming a bit more complicated.

Various types of incandescent (as opposed to fluorescent) light sources differ significantly in color temperature (that's measured in degrees Kelvin, and that's what the WB setting compensates for). Halogen lights usually have higher color temperatures than traditional ones, and within the same class lower wattage bulbs have lower color temperature (more reddish light) than higher-wattage ones. There is no one incandescent setting which would fit all these sources equally well.

Because of that, you may choose to use the Auto setting when shooting under incandescent light. Under most living room conditions most cameras (including all Olympus models I've tried) tend to undercompensate somewhat, leaving the images on the reddish side. This is not necessarily a wrong thing, as the warmer tint gives the pictures a specific atmosphere.

Still, if you want a truer color rendition (whatever "truer" means here; the scene is basking in a reddish light!), you will be better off avoiding the Auto setting. With no doubt, I'm getting the best results with the white balance set by reference (Olympus refers to it as "One Touch WB"), and this will be discussed a bit further down this page.

Under typical incandescent light (read: my living room), the Incandescent (3000 K) preset, designed probably to work with higher-wattage, less reddish, lamps, tends to results in images slightly too warm for my taste. You may want do devote the Custom White Balance (CWB) slot to your own, lower color temperature preset.

This is described in my E-500 customization article; I wouldn't recommend resorting to this option often: assign the slot to something you will be using most often, and keep it there.

Just for the record: you can do it without using the menu system, if not in the most intuitive way:

  • Highlight the WB setting in the Control Panel using the cursor keys;
  • Use the control wheel to scroll it to the CWB setting;
  • Hold down the Exposure Compensation button, and
  • Turn the wheel to dial in the desired color temperature value.

(The trick in points [3] and [4] also works when the CWB option is selected in the menu.)

Another option, also not my top choice, is to introduce WB correction to the incandescent setting (ibidem). Once again, I think this should reflect your preferences rather than the shooting conditions, therefore I am rather against changing it in the field. Reference WB will deliver better results anyway.

The situation with fluorescent light is even more confusing. Fluorescent light does not provide a full, continuous spectrum of light wavelengths.

Actually, the discharge in fluorescent tubes generates only a number of separate wavelengths; luckily, various tube models available on the market have a layer which absorbs that and re-radiates light in a more continuous spectrum, more pleasing to the eye but still not following a standard black-body (thermal) distribution shape. If you are not a physicist, the only thing you may have to remember of this is that (a) some tubes may provide a kind of light for which color rendition will be a tricky task; (b) color temperatures quoted for those tubes are not actually color temperatures (that's why they are often referred to as "equivalent"), and adjusting your camera for these kinds of light is usually more than just moving the color temperature slider.

All that said, the bottom line is that many cameras provide WB setting for a number of fluorescent tube types. So does the E-500, with no less than three fluorescent presets: Fluorescent 1 (4000 K), Fluorescent 2 (4500 K), and Fluorescent 2 (6600 K), with color temperatures, quoted after Olympus, being the "equivalent" ones. The manual refers to these tube types as "white", "neutral white", and "daylight".

Our eye accommodates not only to light intensity, but also to its color, so there is no easy way to guess which of the three fluorescent presets matches best the actual tube type used. There are three ways out of this mess:

  • Use the Auto WB setting: the safest way, and, surprisingly, providing quite good results (better than under incandescent light anyway);
  • Take a set of three test images at three available presets, choosing the best one, and making a note (like: "Aunt Minnie's kitchen: FL 2");
  • Resort to the Reference WB option ("one touch WB").

The only way to go really wrong under fluorescent light is to use the wrong kind of preset.

One day I may come up with a series of comparative samples shot with the E-500 at various settings; for the time being you may refer to such a series I've shot for the Olympus C-5050Z.

White balance in mixed light

The easiest way to have the white balance totally messed up is to shoot under mixed light, like in a living room, with some fixtures using fluorescent, and some others — incandescent light sources (and, possibly, with some daylight from the windows thrown in). This almost guarantees that different areas of the image (highlight, shadows) will have different color tints and no smart Auto WB feature, or no amount of correction in postprocessing (unless you want to correct WB differently in different masked areas) will help you here.

In such situations the best you can do is to remember to never do it again; you may also convert the image to monochrome just to hide the total WB disaster.

This happened to me a couple of times, when doing a quick-job tabletop photography with one kind of light and forgetting the room light fixtures of another kind. Even with the room light being quite weak compared to my tabletop lights (that's why I neglected them), the shadows left by the main source were clearly off-balance. This is the hard (and best) way of learning things...

Setting white balance by reference

This is my favorite way of setting the white balance for pictures shot indoors. It is fast, reliable and accurate; it worked most of the time in the Olympus E-10/E-20 cameras, was strongly improved in the C-5050Z (that's when I got hooked on it), and continues to work very nicely in the current Olympus SLR models.

It may sound like a hassle, but it is not: you do not have to perform the operation before every picture, but only when entering a new interior, with its specific light type (be it incandescent or fluorescent).

Performing the operation takes less time than describing it: point the camera at a neutral (white or gray) surface, hold down the Reference WB button, and press the shutter release. The camera takes a test picture, showing it on the LCD display; if you are happy with the result, press the [OK] button, otherwise repeat the operation pointing at some other surface.

This not only performs the measurement, but also switches the camera to Reference WB from whatever setting it was using before. The measurement will be now used any time the Reference WB is selected, even if the camera has been used in other WB modes.

Strangely, there seems to be no easy way to cancel the operation if you are unhappy with the sample shown; you have to accept the setting or re-try, and only then you can go from Reference WB to something else.

If the neutral reference surface is not uniform enough, or contains brightly-colored objects, the camera may display a "WB NG RETRY" warning, but it is not really fussy about it; in my experiments the E-500 was doing that only if I did something really stupid, like having a bright red subject covering most of the frame. Still, I believe that using a uniform, neutral surface is the right way, as it really tells the camera: "this is what I want to be rendered neutral". A piece of white paper, a white tablecloth, or a white shirt should be good enough.

Anyway, the method is really accurate and offers, I believe, the best results, and it is quite fast, requiring just three button presses: Reference WB, shutter release, and [OK] (that's perhaps why Olympus calls it "one-touch", somewhat stretching the terminology).

Selecting the Picture Mode

This is like choosing between five pre-defined film types (two of these being monochrome). I would recommend these Picture Modes to be set once, tweaked to your liking and then left alone, as described in detail in my E-500 Preferences article. Changing them all the time will lead you to non-predictable results.

Even switching between the preset modes should be done in moderation. I would recommend against doing it back and forth within the same shooting session; it will make the results inconsistent; also postprocessing of your images will become more difficult. After gaining some experience with your mode presets you will be able to decide which one to use for which occasion. Actually, I spend 95% of time in my Natural mode.

Image gradation

This parameter adjusts the tonality of the image, mostly the mid-tones, towards dark (low-key) or light (high-key). From my limited experience with this feature of the E-500 it looks, however, that the highlights and lowest shadows are also affected. I prefer to apply such effects in postprocessing, leaving this at Normal.

Still, feel free to experiment; just remember to go back to Normal when you are done.

Metering pattern

If you are tempted to switch between different metering patterns while using the camera, don't. Listen to me now and thank me later. Still, if you insist, you can set the pattern either from the Control Panel (both simple and detailed view) or using the button dedicated to this function (left-arrow).

The E-500 offers three metering patterns: ESP matrix, center-weighted, and spot. My recommendation, discussed, again, in the E-500 customization article, is to preset the camera to ESP matrix or center-weighted (the latter only if you have a clear preference for that method), and leave it there.

From the menu system (only) you can define how the ESP matrix metering will work whenever you switch to it: with or without an emphasis on the area around the AF sensor used.

If you follow my customization advice, you will not be giving up the spot-metering capability (a powerful tool when knowingly used), as my recommended presets assign spot-metering to the AE-lock function, activated with the [AEL/AFL] button.

Spot metering is intrinsically linked to exposure lock: after all, how often do you have a spot at the standard brightness level exactly in the center of your frame? You just have to lock the exposure when using spot metering, as only you know what do you want to put at the standard gray level; if your settings assign spot metering as the regular (i.e., non-AEL) mode, you will always have to half-press the shutter release and recompose. In my arrangement, you switch to spot just by holding the lock button; if you do not use the lock, you will be using the (safer) matrix or center-weighted pattern.

The spot-metering functionality, when used without understanding, leads to unpredictable results. I have received quite a few emails from users of various models, complaining that their exposures are not right, even though they've "switched the camera to the spot-metering mode" (well, it is advertised, so it must be better, whatever it is!). It turns out that those people are using spot metering without AEL lock — this means the camera is setting the exposure based on the very center of the frame, regardless of what actually is there: a white face or a black tuxedo; this is almost as good as not metering the exposure at all, possibly worse, being totally random.

The two extra spot-metering modes ( spot-highlight and spot-shadow) do offer some extra functionality at the expense of being even easier to misuse. I'm skipping them in this write-up: if you really need them, you probably should not be reading, but writing this article.

Auto-exposure and/or autofocus lock

Normally, the camera meters the exposure at the moment the shutter release button is half-pressed. The exposure remains locked (i.e., shutter speed and aperture will remain as set at that moment) even if you re-point the camera to a brighter or darker area, as long as the release remains half-pressed. This means instructing the camera: "take a picture here, but estimate the correct exposure in this place, which I (the photographer) consider better for that purpose".

A typical use of this feature is when taking a picture with a large area of bright sky: most of the frame is bright, so that the camera may underexpose.

If you lock the exposure with the shutter release, the camera will use your pre-set metering pattern as discussed above; it will also lock the autofocus — unless you've changed that when setting your preferences.

Another way to lock the exposure is by pressing and holding down the [AEL/AFL] button. This does not lock the autofocus (which may be still locked with the shutter release button, at least in the single AF mode); the method also allows you to assign a different metering pattern to be used when the lock button is pressed; see above, again.

The way in which the lock button and shutter release work together (regarding autoexposure and autofocus lock) is customizable; I consider my recommendations to be at least a good starting point. In any case, this is not something you should change from day to day.

Focusing mode

Using the Control Panel, or the dedicated (right-arrow) button, you can quickly switch between three focusing modes:

  • Single-frame autofocus: the camera focuses when the shutter release is half-pressed, and the focus remains locked until the picture is taken, unless you lift your finger off the release;
  • Continuous autofocus: the camera starts autofocusing when the release is half pressed, and keeps updating the focus until the shutter is actually released.
  • Manual focus: the photographer may set the focus by hand (i.e., turning the focus ring on the lens), using the finder image for feedback, as tiny as that image may be.

Obviously, in most situations you will be using single-frame autofocus (SAF), as it is more accurate and uses less battery, switching to the continuous AF mode only for rapidly moving subjects (sports, children).

The manual focus (MF) mode is, well, manual, and I resort to it only with legacy (non-AF) lenses, which must be used with an appropriate adapter. With my middle-aged eyes and the tiny finder in the E-500 (well, just 10% smaller than in competing models, but still small), I trust the AF more.

Still, my preference setup for the E-500 introduces an interesting variation on the subject: assigning the [AEL/AFL] lock button to a one-shot autofocus when the camera is in the MF mode: AF on demand. If you are planning to use manual focus, you should try this option (obviously, it will work only with AF lenses).

AF point selection

This option is accessible either from the full version of the Control Panel or via its own dedicated button. You can force the camera to use a given AF point (out of three available), or allow it to use all three and to choose the reading. Olympus does not provide any details of how the choice will be made ("just trust us, and everything will be just fine"), but the selection is shown by a blinking red LED overlay in the finder.

I suspect the system tends to use the center sensor whenever possible: this sensor is sensitive to both vertical and horizontal lines, reverting to one of the side sensors only if the center one does not have enough detail to focus on (the side sensors can focus only on horizontal lines, assuming your frame is positioned horizontally).

It may be a matter of your working habits, but I consider the AF point setting not to be a very useful feature, unless the camera is used on a tripod. When shooting from hand, I find it more convenient to check which of the three AF lights blinked, and if I don't like the choice, I may point the camera where needed and lock the focus and exposure with the shutter release button, then re-frame and shoot. The only time I'm using this option is when I want to disable the side spots at all, to gain full control over AF.

Checking the red AF confirmation signal in every shot is a good idea anyway. You don't want the camera to focus on distant trees between the heads of your models. You know what you're shooting; the camera doesn't.

Anyway, the button is there; I sometimes regret that it cannot be re-assigned to some other function.

Drive mode

The name of this setting is a remnant of times when you actually needed to attach a motor drive to your camera in order to shoot serial pictures, without cranking the wind lever before exposures.

The E-500 allows you to switch between two drive modes:

  • Single-frame, where the shutter release has to be depressed for every picture;
  • Sequential, where the camera will keep shooting frames every 0.4 of a seconds while the release is held down — or until the image buffer is full.

The buffer fills up after four frames in raw ORF and TIFF image format modes, as well as in SHQ. For HQ and SQ this depends on image compression and (in the latter case) pixel dimensions. If you use the 1:8 (or 1:12) compression ratio, you will be able to keep shooting until the card is full.

In my customization presets, see also below, I recommend setting SQ as 3200×2400 pixels (almost full native resolution) at 1:8; this allows for unlimited frame sequences, and the 1:8 compression is as good as the "high quality" setting on some other SLRs.

You have to keep in mind that both exposure and focus are locked before the first frame in the sequence; this makes sequences longer that three or four frames not really useful anyway in action shooting. They may be, however, useful, when you use any of the bracketing functions, as described further down.

The "drive settings" also include a self-timer (with 12 or 2 seconds of delay) and infrared remote (no delay or two seconds). Both can be useful in tripod-based shooting, as the E-500 is missing the wired remote option. (I hope Olympus may still come up with one, using the USB/AV socket, which can already be used for remote control from a computer, if you have the optional Olympus Studio software. The wiring is there!)

Storage card

You may switch quickly between both cards plugged into the E-500 (Compact Flash and xD-Picture) right from the Control Panel, using the normal highlight-and-turn metaphor. How and when you do it will depend on your personal preferences. I usually save images to a CF card, using the xD only when running out of space, which happens less and less often as CF capacities increase. CF cards are usually faster; while Olympus recently announced a faster xD type, I will believe that only when I run my own comparison; some earlier claims regarding the xD standard turned out to be overinflated.

Another thinkable procedure, which I haven't used yet, may be to shoot to one card, and copy the most valuable images to the other, just to avoid an accidental data loss.


Bracketing is a shooting technique where a sequence of images is taken with a value of a particular setting (most often, exposure) slightly changing from one frame in the sequence to another. If the adjustment is done by the camera, not manually by the user, we refer to this as autobracketing. This technique was especially useful in film photography, with no means of checking the results before the film was developed.

The E-500 offers bracketing in three variables: autoexposure (with or without flash), color balance, and focus. All three (or four, depending on how you count) are operated in a similar way.

First, the camera has to be set to bracketing mode. This is done from one of the corresponding entries in the Camera 2 menu, as described below. The setting not only activates the feature, but also defines the number of frames and parameter adjustment magnitude from one frame to another. The autoexposure, flash, and focus bracketing are mutually exclusive (i.e., only one can be used at a time), but WB bracketing can be used on top of any other kind (although I doubt you want to use this option).

Now, things are getting a bit messy. In most film cameras pressing the shutter release once the autobracketing is set will cause the whole frame sequence to be shot. Not so in the E-500: each frame in the sequence requires, by default at least, a separate shutter release operation. (An exception to this is white balance bracketing, described above, where just one frame is shot, but it is then converted to RGB in a number of ways.)

This behavior can be modified by setting the drive mode to serial. To shoot the whole sequence at a time you will have to keep the shutter release pressed until the sequence ends, but at least the series will stop after that, even if the button is still pressed. This works fine in the most typical case of exposure bracketing, where the sequence has the fixed length of three frames. It does not, however, in WB and AF bracketing, where the sequences can be longer. Depending on your quality (image compression) setting, the serial mode may run out of buffer space, and the series of quickly shot frames will be interrupted before the whole bracketing sequence is taken. To continue, you have to press the shutter release again.

All this means that, whether you are using the serial or single frame mode, you may end up with only a part of the bracketing sequence shot. The next picture you take (right away or the next week, as the bracketing status is not reset by turning the camera off and on again) will have the bracketed parameter adjusted according to its number in the sequence.

Therefore, regardless of the kind of bracketing you are using, you have to remember two things:

  • The presence of a small [BKT] symbol in the Control Panel means that one of the bracketing modes is active (with no indication which one). If the symbol is blue, this means that a bracketing sequence is underway (otherwise it is black).
  • A partially completed bracketing sequence can be reset by turning the Mode Dial to some other position and back.

Autoexposure bracketing

This is set as AE BKT in the Camera 2 menu. Depending on the EV adjustment step (as set in your camera's preferences), there are two to four options available here. One of these is OFF, the others define the exposure difference between frames in the bracketing sequence (the sequence length is always three frames); that difference is always limited to 1 EV maximum.

The first frame in the sequence is shot at the nominal exposure (i.e., as measured, plus any exposure compensation dialed in); the second below, and the third above that. Depending on the autoexposure mode, the adjustment is done by changing the shutter speed (aperture priority), aperture (shutter priority), or both (program).

Flash autoexposure bracketing works in a very similar fashion, except that it is shown as FL BKT in the menu. A more important difference is that exposure adjustment here is done by modifying the flash output (burst length) rather than shutter speed or aperture.

Interestingly, using the "regular" exposure bracketing with flash seems to be working in exactly the same way. Therefore the only reason of having flash bracketing as a separate option might be that it will have no effect when shooting without flash, although, to add to confusion, in such a case a bracketing sequence will still be shot, albeit with all frames exposed identically.

My advice: forget the flash bracketing at all; use the regular one instead.

Focus bracketing

Olympus refers to this as manual focus bracketing, and the feature is accessible as MF BKT from the same Camera 2 menu as the other bracketing functions. It works only when the camera is in manual focus mode, but using an autofocus lens — as it uses the focusing motor in the lens.

Therefore, at the first glance at least, the feature may seem to be of marginal only usefulness, but this is not the case. Yes, I would prefer to see focus bracketing available in the AF mode (where the AF may be done on the critter's whiskers instead of eyes, a meaningful difference with a long lens wide open). A simple work-around, however, allows us to enjoy this functionality.

This is achieved by switching to the manual focus mode, but using the AF "on demand", assigned to the AEL/AFL lock button. This assignment is described in my E-500 settings article, and the whole idea is discussed elsewhere, so I will not repeat all details here. Let me only mention, for the record, that focus bracketing offers a choice of five or seven (!) frames, with frame-to-frame differences set to one or two arbitrary "steps".

White balance bracketing

This bracketing, shown as WB BKT in the Camera 2 menu, is quite different from the above: the camera takes just one exposure, but then saves a number of files, with white balance being adjusted in processing. The adjustment can be done in the Blue-Red direction and/or in the Green-Magenta one, therefore you may end up with three or nine frames (three frames per direction, both directions used).

This feature is not really useful: if you feel a need to "bracket" the color balance, set the camera to raw image file format and adjust the balance in postprocessing. You do not gain any advantage by using this function, and therefore it is safe to ignore its existence.

(Note that the same is not true about exposure bracketing: once a raw image is over- or under-exposed, the lost information cannot be retrieved, therefore shooting raw does not give you any, or almost any, protection.)

As I have already mentioned, WB autobracketing can be used "on top" of any other. This may lead to up to sixty-three files saved from a single sequence: seven focus positions times three WB ones in the red/blue plane times another three in the green/magenta dimension. Looks rather excessive.

Another quirk of this function is its accessibility even in the raw mode. As a result, up to nine raw .ORF files will be saved, all with exactly the same image data, just with different in-camera WB information, which will usually be overridden anyway in postprocessing.

Flash use and compensation

My preference setup disables the flash auto-popup, for a number of reasons. I think anyone who buys an SLR should be legally obliged to know when to use flash. Therefore my customized E-500 requires the flash-up button (top left) to be pressed to raise the built-in flash, and, once raised, the flash will fire every time, regardless of the ambient light.

The built-in flash, anyway, should be used for two purposes only:

  • As an emergency measure, when you must use a flash and you don't have an external unit; in this case you have to accept the fact that your pictures will come out ranging from mediocre to awful;
  • As a fill-in light when shooting in bright outdoors light, to soften the shadows. (This use deserves a separate article; maybe one day...)

(Unfortunately, the possible third use, as a fill light with an external unit, is not possible with the latter mounted on the camera's hot-shoe; the mechanical constraints do not allow the built-in flash to be raised then, unlike in the E-300 or E-330.)

Whether with an external or internal unit, there is a question of exposure compensation. A separate setting for this is included in the Control Panel, and it is up to your preferences whether this compensation will be applied on top of or instead of the "regular" compensation, dialed in when pressing the compensation button.

My choice is the former ("on top"); refer here for more details on how and why. In such an arrangement you should be using the extra flash compensation only if your images with flash tend to be off the mark as compared to ones without.

The Olympus FL-36 flash is a well-matched companion for the E-500. When using it, you have to keep in mind that it has its own compensation setting (set with an external dial in the unit back), and this setting is applied on top of whatever you've set up on the camera — so that the total exposure compensation may be a sum of three separate settings.

Flash photography with the E-500 is a separate topic, deserving its own article. In particular, the co-operation between the autoexposure system and the flash unit is somewhat different than I first expected (although for some good reasons). One day I hope to be able to move this section out, and have the new article under way, but no definiotive promises. One thing at a time.

What next?

This article does not try to replace a full, detailed reference manual the E-500 deserves and is sadly missing. It is just a public service attempt by a single individual, a peer-to-peer effort. If you find any features' descriptions missing or misrepresented, let me know.

The article has been significantly expanded and enhanced since the original posting, but it still remains a work in progress. At this moment, my to-do list starts from flash photography and image review.
