On my system, a ThinkPad T42p with Flexview 1600x1200 LCD display, the DISPCAL program tends to produce calibration curves at about 2.0 gamma instead of 2.2 gamma (the default). Then when the profile is applied to an image the gamma seems to be corrected by the profile back to about 2.25 or so. Is this the intended behavior, am I doing something wrong, or is there some other explanation? Thanks,
There is some fun and games with how the black point is handled (do you subtract the black point from everything, or ignore it and aim zero at absolute black ?), but no, it's not meant to be like that. How are you determining that the gamma of the display after calibration is 2.0 ? Graeme Gill.
