So you're saying that the linearity of the camera (once you take out black point) is so good that it's reasonable to just computate a matrix, rather than also having a linearity correction curve. I looked at a profile of my old notebook's LCD that was created with an Eye-One spectrophotomer, and it was definitely non-linear. But it does seems that everyone assumes the cameras are linear. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
