Even the best digital cameras are incapable of consistently delivering accurate color without the user performing a custom white balance. Auto (AWB) and preset white balance functions often produce maddeningly inconsistent results. Images shot without a correct white balance may have unnatural looking red, yellow or blue tints that are time consuming and difficult, if not impossible to correct.

Recognizing the importance of custom white balance to good color, digital camera manufacturers have designed their cameras to take advantage of a custom white balance. A custom white balance calibrates the camera to the exact color temperature of light illuminating the subject.

The ExpoDisc is a custom white balance filter that allows digital photographers to quickly and easily set an accurate custom white balance. Consistently producing excellent results in natural, artificial, and studio lighting, the versatile ExpoDisc even excels in difficult mixed lighting environments.

The ExpoDisc is far easier to use than any gray card, white card or calibration target. Simply place the ExpoDisc in front of your lens and capture the incident light while setting your camera's custom white balance. Using an ExpoDisc custom white balance will virtually eliminate the need for RAW or JPEG post-capture color adjustments.

ExpoDisc technology takes a unique approach to setting a custom white balance and producing accurate color. The ExpoDisc essentially uses your camera's built-in custom white balance capability to turn the camera into an incident color-metering tool. This approach avoids the common problems and inconveniences associated with using gray cards, white cards and calibration targets: unwieldy size, unwanted reflectivity, improper angling and difficulty of filling the fr

Customer Reviews

Invaluable tool used in the field.
The first thing I did when I bought the Expodisc was shoot a yellow wall with incandescent lighting. This is the most dramatic example of how the Expodisc makes you realize your camera's auto WB is worthless. Your camera sees a yellow wall with yellow lighting and overcompensates by making everything bluer than it should be. Expodisc only cares about the color of the light source, so it only removes the yellow cast of the incandescent light.

In the example above, a grey card may have been SLIGHTLY more accurate due to the yellow walls surrounding the light source and therefore some ambient color cast infiltrating the disc's view. But in 95% of normal scenarios, this little tool will be just as accurate and far more convenient.

Another note: if you are new to color calibration, be sure to thoroughly read the instructions for the Expodisc. Because used improperly, this tool could produce horribly inaccurate results. Used properly, however, you'll find that it's as useful as a grey card without the hassles of a grey card. Just pop it on your lens, aim toward the light source, and you've got yourself accurate color balance!

If you shoot JPEG images, this will fix your white balance in any lighting condition
All you do is put this filter on your lens, point the camera to the main light source at your location and set your camera's white balance to that light source and the pictures come out with perfectly-balanced colors.

If you own a Canon SLR and shoot mainly in JPEG format (Canon's auto white balance-especially in low-lit scenes, gets it wrong every time!), this makes getting good results very easy.

I can't speak for the auto white balance capabilities of cameras other than Canon since I don't have any experience with them. I know that some cameras do very well on their own. Check your photos: If your JPEGs appear to have unnatural color and the whites are off, you may benefit from Expodisc's prowess.

If you shoot RAW images and do your own post-processing, you will most likely not have much of an need for this gadget as you will be able to adjust the white balance to your liking regardless of the camera's default settings.

Solve your color managment problems before the shot...
I would much rather spend my time taking pictures then working in the digital dark room trying to figure out where my white balance should be set. For those that are new to color management in a digital world it is all about measuring the type of light conditions you are shooting in. Early in the morning when the sun first comes up the colors are very vibrant versus later in the day when the sun is high, color is much more subdued. Well with an ExpoDisc you can now take a picture and know exactly what the light conditions are. Set your white balance in the camera now and when you get to photoshop later you don't have to guess. To easy to use.
