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.

I bought this to show my students the various ways to set white balance. In the tests we conducted in class it acheives slightly better performance that a standard white card but is much easier to use. I would imagine for action photographers it would be a big help as you wouldn't have to be juggling the card set around when setting balance. Now that I have it I will be using it quite a bit. It is also very well made and the unique mounting system works like a charm.

Found it very useful, especially with my old F3 and D1.

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.
