ExpoDisc - Digital White Balance Filter - Neutral for Professional Digital White Balance
The Expodisc is used in place of a white card to set manual white balance. It looks like a fat filter with a fluorescent light fixture diffuser on top and white plastic on the bottom.
You don't photograph through it. You put it over your lens and put your camera in the same position as your subject. Point the camera back to your shooting position. Set the camera's white balance while it measures the same light that will fall on the subject.
Once set, put away the Expodisc and shoot from your original position. You don't shoot through the Expodisc, except to set the WB.
It turns your camera into an incident meter. Incident meters measure the light falling on (incident to) the subject. They don't measure light reflected from the subject, as most meters do.
A great tool.
