Levels

One of the most powerful tools available in post-processing photos is the Levels editor. It displays the picture's levels histogram and allows you to manipulate it with a few simple but effective controls. After this lesson, you will understand what a levels histogram can tell you, and how you can use it to greatly improve the color balance and tonal range of your image. Your pictures will gain a lot of zing: the colors will be brighter, the shadows richer, and the highlights brighter without having lost detail.
