In Photoshop, the terms ‘highlights’, ‘midtones’ and ‘shadows’ are used for the dodge and burn tools and for the eyedroppers in Levels and Curves.
What range does each term cover? Is it evenly divided 1/3, 1/3, 1/3 so that shadows would be RGB 0-85, midtones, 86-170 and highlights 171-255.
I got thinking about this when someone suggested to me that he likes to ‘boost the cyan in the blacks’ to get better printed blacks. I didn’t question it at the time, but having now had the chance to give it some thought, I don’t understand how one can ‘boost the cyan in the blacks’ without affecting the rest of the image?
Has anyone else used this technique to improve the quality of printed blacks?
If one sets the RGB values for the shadow eyedropper to, say, 5,5,5 to what level of RGB value will the parts of the image be affected?
