Aaron,

I did try a "Pringles" lid, which is supposed to be very similar in function and results. It just doesn't seem necessary. Any white in the scene can be used by a modern dSLR or digicam to measure for white balance.

A common trick is to add a white circle of paper to the inside of a lens cap, and use this as a white target.

should you?
shjould you set the white balance every time you do a shoot? I usually just keep the white balance on auto and every thing else on manuel.

I usually set WB on auto, unless in a mixed light situation. In that case, I try to figure the dominant light source, and set to that color temperature with a preset or manual WB. I usually use a sheet of white paper, that I carry for the flash, for the white target.

In the worst case, I'll shoot RAW and sort it out later.

I've used the expodisc a couple times. I ALWAYS shoot raw, but having this "filter" has speeded up PP quite a bit in that I don't have to fiddle with the WB in ACR all the time.

Do I use it all the time. No. Outdoors and when there is only one light-source, the camera get's it figured out pretty close. Other times, it sometimes needs a little help and the expodisc has come in very handy.

I have had both the Expodisc and the Whibal cards and sold the whibal because the work flow was longer, I shoot raw and use the expodisc all the time with great results...
