My question is: will the histogram in Lightroom look different when the monitor profile is changed or should that allways look the same on the same raw image in lightroom and is independent of the monitor profile? I ask this because I recently updated to Windows 10 and had to recalibrate my monitor with Spyder3 (which is not officially compatible with win10 but does do some calibration...). Now I think I have an issue with the black point of this profile, because many images I work on in Lightroom now have a small flat line on the left side of the histogram and I need to lower black point for each of them. Is it possible that my monitor profile is wrong? Or does the histogram only show the values of the RAW image without considering the monitor profile?
