Get accurate color in difficult lighting with the patented ExpoDisc, the fast and easy digital white balance filter. Simply read and set white balance with the ExpoDisc in place before shooting and you'll reduce or eliminate the need for post-capture color adjustments. Get the white balance solution that is quickly becoming the preferred method of achieving accurate color balance for professional photographers today. Here is how it works: Varying levels of colorcast typically occur in digital photography and require compensation as part of the process to create a photograph with good color fidelity. Until now, photographers have had to rely on gray/white cards to solve this problem. The ExpoDisc is an easy to use custom white balance solution that eliminates the inconvenience and inconsistencies of other methods. It is a neutral diffusion filter that gathers ambient light and passively transmits 18% of it through to your camera's light meter, effectively producing a "gray frame". You then set a custom white balance using the "gray frame" that results in accurate color in most lighting conditions. Your camera essentially compensates for and neutralizes the colorcast it sees through the ExpoDisc.

Conclusion: Expodisc: practically unique function, but pricey
Review: I bought the current Expodisc to replace an earlier model recently stolen. The old model seemed overpriced, but it was hand-made in a low volume production. Current models made by new owners are priced about 170% more than the old, for which you get a fancy box and a few instructions on a CD rather than on a peice of paper - big deal. However, the new models have a lens mounting arrangement which is much superior to the prior model and much more expensive to make. As to function, nothing really replaces an Expodisc if you need one for white balancing a color photo exposure. I use mine to shoot "grey" color negatives to automate traditional color printing. I have no experience as to whether they provide superior white balancing in digital systems as claimed, but logically they should do so. Unless you plan to be very exacting about color reproduction in your color printing, the excessive cost of an Expodisc versus the marginal benefit seems questionable. If you Photoshop your pictures to death, you will get no value from this item.

Conclusion: Custom White Balance with ease
Review: It works as advertised and does what it's supposed to do. Aside from that, It seems to do a perfect job of correcting WB despite multiple combinations of types of light. As they say, "It's so easy, even a caveman can do it!."
I only had a problem with one particular type of light which I believe was a High Pressure Sodium (HPS), which put a yellow color cast on everything while in the custom WB mode. (This type of lighting is used in our local convention center.) Aside from that, you can throw away your 18% gray cards and or your white cards. Expodisc is all you need, period!
