Justin,
I have not tried it, but I was told in a digital imaging class that the lid
from a Pringles potato chip can would also work the same way.
www.expodisc.com ( digital white balance filter).
Dear Douglas.
This reccomendation to go chip ( and cheap) with your White Balance calibration is a fine formula to learn dealing with strange hues all across your entire shootings. You will do better by picking a default camera setting, like Daylight. Believeme, I've been there.
OTOH, the Expo disc is by far the best tool to define Custom White Balance you may find on the market. It is particularly suited for those who rapidly change lighting scenarios, and indispensable for those who require total color control ( like when shooting fabrics, swimmwear, and colored outfits with changing lighting situations) and you need sustained and accurate color renditions, like when shooting in several days under different scenarios, and samples from day 5 , shot under sunny conditions, have to match samples from Day 1, shot under tungsten, while you mixed daylight and strobe the 3rd day.
However one very simple workaround when you miss the disc at home is to just set one and only one Wb setting, don't mess with it, and run the appropriate color compensations in the RAW processor of your choice. Of course, if you are using JPEG or TIFF for your shootings ( assuming we can say those formats resemble slides regarding their limited options for Post manipulation), then carry around your ExpoDisc all the time with you and be happy. Carry a can of Potato chips around, but use it only for munching activities.
Potato chip covers also work fine as mini frisbees.
