You can use the Quick Selection tool in Photoshop to easily select and edit specific parts of a photo. Once you've made your selection, you can delete or edit that section without affecting the rest of the photo. Anything you've selected with the Quick Selection tool will be surrounded with a black-and-white dotted line. When you're working on an image in Photoshop, there are times when you'll only want to edit a specific part of the picture — maybe someone's face, or just the background. If this is the case, then the Quick Selection tool is your friend. Like other selection tools, Quick Selection lets you pick a section of the picture to work on. But unlike other tools that make you pick out the section manually, the Quick Selection tool uses colors to better select only what you want.
