I would like to understand gamma and color management, but it’s confusing, hope someone can review and reply to the following.
I am assuming that I understand the following: our computer monitors have a non-linear response curve which reduces the brightness of mid-tone pixels viewed on the monitor. This is the monitor’s “gamma”, based on hardware, math, voltage, whatnot. The typical monitor gamma is 2.5, which results in darker mid-tones. “Gamma correction” on most systems is 2.2, which means that the monitor’s gamma is reversed by that much before display, so images look “correct”, ie brighter than they would without correction.
Now if that is correct, I am happy, but still confused. Are images themselves managed beyond the gamma correction of the os or video card? We have the monitor darkening the image, the correction brightening it back up, right? Then what about Photoshop color management? Is that another step?
thanks for reading,
