A visual scale based on black and white stripes will (probably) be a power curve offset at zero, because it is composed of a real black that is non-zero. Naturally, these two different ways of interpreting gamma are not the same.Hello Graeme, I still have no idea how to calibrate monitor properly. Please look here: http://img72.imageshack.us/img72/8079/outputx.jpg
I see you're using 'very low' calibration quality (-qv parameter). This means only little effort will go into actually matching your chosen target values. I'd at least use low or medium imho.
it's clearly visible that actual output from my monitor (at 50% input) is a little bit darker than actual target. It should be corrected at LUT level by slight brightening at 50% input what perfectly corresponds to my visual observations. Unfortunately after calibration I have curves like this: http://img695.imageshack.us/img695/1075/curvesz.jpg so my question is - why is it happen and how to avoid it?
