Since I got two responses for spheres, I'm not sure if I explained my
question correctly. I am using the Sinar CaptureShop software to do
what they term a "Scene Reference", which is also known as
flat-fielding. It corrects for light fall-off and spatial
non-uniformity of the light due to other reasons. I capture an image of
a white card to determine the nature of the light
fall-off/irregularity. In order to work well, it is critical that the
card is very uniform on the surface.
My question is pertaining to materials for the white card to take the
image of since I am not completely satisfied with the ones that we are
currently using. I don't understand what a sphere would have to do with
this, but if I'm missing something, please explain.
Thanks!

Translucent white plexiglass?
