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.

I LOVE the ExpoDisc !
I take hundreds of pictures in night indoor settings with difficult lighting conditions - multi-colored lights, and mixed lighting sources. Even though I have a great Canon EOS 20D camera and several very nice lenses, I still had a terrible time with white balance with people looking too gold or gold-green or red. After each session I would spend 8-12 and more hours correcting all the pictures in Photoshop. With the ExpoDisc, and carefully using it following the instructions that came with it...View full Review
I take hundreds of pictures in night indoor settings with difficult lighting conditions - multi-colored lights, and mixed lighting sources. Even though I have a great Canon EOS 20D camera and several very nice lenses, I still had a terrible time with white balance with people looking too gold or gold-green or red. After each session I would spend 8-12 and more hours correcting all the pictures in Photoshop. With the ExpoDisc, and carefully using it following the instructions that came with it, and the camera settings, my pictures are now coming out great right out of the camera, saving me hours of post processing work. My experience with digital cameras is that all of them are difficult to get the white balance right, and the ExpoDisc is the best tool I have found to solve this problem. One of the neatest things is that you can use the ExpoDisc as a lens cap, so it is always handy for use to set the white balance.

Falls off every UV Filter I tried
I tried to put this on after the UV filter, but it kept on falling off. Tried different UV filters to try to get more for it to hold onto, but no luck.

The ExpoDisc is perfect and wish I had bought one long ago.
I was happily suprise how easy and precise the white balance calibration could be done with EXPOD52. Can't live without it and going to buy one more. :)
I saw the expodisc last year and thought it would be neat, but did not purchase it. I just bought it and love it. I should had gotten it sooner. It fits in your pocket, take it out, hold it over the lens and set your custom white balance. It is that fast. I use it for indoors at church and for weddings. I don't think it is needed for outdoors.
Great for white balance in the field. Replacement for a white balance card that's awkward to carry. Also great when you don't want to ask the subject to hold a card. For studio work, I use a Porta Brace White Balance Card. The ExpoDisc easily clips into the lens that I use most of the time. Slight disadvantage: it neasures incident not reflected light. The camera has to be pointed at the light source. I'll do some testing to see if there's a big difference between incident and reflected. Good gadget to have in the pack I hike with.
WB doesn't get easier than this. Always right and no big targets to cart around.
Such an easy product to use and saves so much time! I highly recommend this product! I bought the larger size so I can use it with all my lenses and it has worked great!
Easy to use
Indoors with natural light, I think it really works great! I'm still getting the hang of it outside in natural light conditions. Even though it's the neutral one, my results still seem really warm when used outside. I will there was a neck strap on the disc itself instead of on the case.
It worked fine and easy to use.
