However, for each sort of physical color primary set (i.e. for each type of display) a special set of bars can be made so that the filter comparison method works. > > If we may assume that Doug has calibrated his > display > with the (D)VE disc and the filter(s), then he has > actually calibrated it wrong.

That's correct ... the green should be and is oversaturated, and yellows should look a teensy bit greenish. This actually happens. You can, of course, adjust the tint to make skin tones correct if you wish. But skin is red enough not to matter. But on my set, which came with a horrendous red push, if is plenty good enough just to remove the red push and then use the "Joe Kane" method. Theoretically you should replace the red push with a green cut to counteract the over-saturated primaries. I think this is possible with my set. > > Disclaimer: I may have a wrong interpretation of the > method of calibrating the saturation with the SMPTE > colour bar picture. I think you are correct. ===== Doug McDonald my last name at scs dot uiuc dot edu, not here at Yahoo, please __________________________________ Do you Yahoo!? Yahoo!
