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. :)

Auto WB is good on my D7000 but in indoor shots with multiple color temp. CCFL lights, colors were inconsistent. This made it a lot easier to correct than in post. Some off-camera correction was still needed to harmonize the color balance across some shots because of point sources. Some reviewers have said it doesn't stay on. I did not find that a problem - it snaps into the filter rings easily using 3 spring-loaded pins. It's not a "firm" hold, but enough that I didn't worry about it falling off. It felt solid enough on the filter mount of my Nikkor 1.4D AF 50mm and when snapping into the filter threads of my Hoya 52mm UV filter, and Vello rubber hood. Definitely an easier product than messing with gray cards.

I use a Nikon D90 which gets auto white balance right about 90% of the time. I kept getting frustrated in unusual indoor lighting situations (e.g. church, rooms with mixed incadescent and fluorescent) becuase the D90's auto WB doesn't always interpret correctly. And, of course, this camera - and I guess just about all DSLR's - have an internal light meter that measure REFLECTED light. This neat little gizmo meters incident light (if you use it according to instructions) and has thus far resulted in virtually perfect white balance for me! The use of this disc is not intuitive. You have to read the instructions carefully and follow them. The process is somewhat cumbersome at first, but is no big deal with practice. My only quibble - it's outer diameter is a squiggy too small. It doesn't snap nor press fit as well as it should on my 52mm lenses. Thus I have to tip it upward a little to assure it doesn't fall out. However, as dealing with all creative geniuses, with all it does so well for me, I can deal with a little temper tantrum. Highly recommended!
