Cropping is an essential skill when it comes to photographic post-production digital editing. The tool allows the user to keep a rectangular section of the photograph while deleting the excess. When focusing on the subject of a photograph, it can be important to remove anything around it or in the background, as this may distract the viewer from the message or aesthetic you're trying to get across. Cropping is also used to make an image conform to a certain print size by cutting out a usually small portion of the photo.
