Photoshop includes a variety of tools to manipulate your images. The Pen Tool includes a freeform function to select any part of a photo. Many options exist to manipulate selected portions of a photo in Photoshop. All of the basic image editing functions such as brightness, contrast, color, levels and exposure work with selections. Additional possibilities such as enlarging portions of a photo are possible with selections.
