dispcal switched the color patch. (It would be nice if there was a dispcal flag to measure the display as calibrated!)
OK, I'll see about adding that as an option to "-r".
Aprox. gamma = 2.01
Ah, well, I think what you've noticed is that between the first release of dispcal and the current one, I changed how the black point was being dealt with. I was originally subtracting it from all the measurements, but in the current version the curves are computed in relation to absolute zero. The "Approximate Gamma" calculation is still subtracting black, and this may explain the discrepancy between the aim point, and the value you measured. I'll fix the code to be consistent for the next release. Graeme Gill.
