Re: GretagMacbeth Digital Color Checker SG

Sheen: That may be a serious problem. I can only use this checker if I
set it up with the same illumination that it was measured under, and
use the same view direction that was used to record the spectral
distribution of the samples. This requires a black environment, I
guess. When and how do they normally use this color checker?

We measured ours with a spectrophotometer. I'll e-mail you the
results.
By the way, we ended up not using it because the sheen was causing
problems in our light booth (which is like a big white integrating
sphere).
