In this step you'll learn about levels in Photoshop. Levels is a tool that allows you to sharpen up the blacks and whites of an image. You can do this by using the black, gray, and white pointers to drag the levels in from both sides. You can also adjust the center slider to get the desired effect. Once you've applied the levels, you can turn the layer on and off to compare the original and the edited image.
