ExpoDisc
ExpoDisc Professional Digital White Balance
Get great color in difficult lighting with the patent-pending ExpoDisc. Whether you’re shooting RAW or JPEG, simply read and set white balance with the ExpoDisc before shooting and you’ll reduce or eliminate the need for post-capture color adjustments. Why spend time fixing color if you don’t have to? Simply the fastest way to Capture Accurate Color.
What is white balance, and why do I need to set a custom white balance with an ExpoDisc?
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 Professional Digital White Balance Filter (patent pending) 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.
How do I use the ExpoDisc?
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. By setting white balance as an incident filter rather than as a reflective target, the ExpoDisc 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 frame.
How did it fair in testing?
The expodisc worked really well in the preliminary tests that I did. I shot a image of white cupboard doors under fluorescent lighting. I will let the images do the talking. This shot was taken with my D7000 set to aperture priority, auto white balance, 200iso.
The next shot was set up using the expodisc. First a custom white balance was taken using the expodisc pointing towards the main light source. The camera was then set to manual mode, aperture set the same as in shot 1 and the camera made a meter reading with the expodisc on. As you can see the expodisc has corrected the wb perfectly and also raised the exposure so the whites are true white not a greyish shade.
As you can see the results are extremely impressive and would conceivably make your post processing workflow at lot faster and more accurate. I would give this product 8/10 as it does exactly what it says it does and really easily. However it's only downfall is the fact that it is fairly pricey. If you do buy one I recommend purchasing the 77mm mount size, this then guarantees compatibility with all but the largest lenses.
