When an image really pops — when it jumps off the page at you — it's generally because the shadows are dark, the highlights are light, and the colors are rich. I'm sure it's no surprise to you that Photoshop can handle the job. (That's one of the reasons why you bought the program, right?)
In this chapter, I introduce you to the concept of tonality, which is the range of brightness in your image. I also introduce to you the various commands that Photoshop offers for you to adjust your image's tonality. There are even a couple of tools for pin-point control of shadows and highlights.
