Hello all, Does anyone know where I could get color filters which simulate the tristimulus response of the human eye? I imagine that minature versions of these must be placed right on a mask in front of color CCD chips, but I am looking for a macroscopic version of this. I would think that these must be pretty common, but I have not been able to find them.
