Subject: Re: ACR Calibration

rags ...

I firmly believe we need the spectral response data from the sensor manufacturers
for accurate color matching.

would that be enough? what accuracy? ball park or strike zone? with those kind of riches, end users might even be able to reverse engineer the tolerances +/- acceptable to a camera maker. methods for scientifically detecting deviances are not the kind of thing camera makers are fond of supplying. after all, ain't they supposed to be all the same? :-)

aside from sample variation, we'd also need to understand some of the color conditioning voodoo from the local witch-doctors guild. hmmm ... was that two shakes of a dead chicken or three? so many questions yet so few answers ... ;-)
