Chapter 5. Optimizing Grayscale Images > Evaluating and Adjusting Contrast

Evaluating and Adjusting Contrast

The middle slider will move when you adjust the upper-right or upper-left slider. This happens because Photoshop is attempting to keep the middle slider in the same position relative to the other two sliders. So if the middle slider is centered between the other two, it will remain centered when you move one of the outer sliders.


The brightest and darkest areas of your computer monitor are nowhere near as bright or dark as the objects you'll find in the real world. The difference is even more extreme when you look at the brightest and darkest areas of a printed brochure—the paper is actually pretty dull, and the ink isn't all that dark. Because of this, you'll need to use the full range of shades from black to white in order to make your photos look as close to reality as possible.
