While tonal and color corrections are important to the overall quality of your image, the chance to really make them shine comes when you start pushing around those pixels. Typically called image manipulation or image alteration, Photoshop gives you all the tools you need to make each picture truly your own. Don't like that tree in the background? Remove it! Unhappy with the color of a purple shirt? Make it blue! With a little planning and an understanding of how these tools work, you'll never have to settle for reality again.
