Clipping a photo is the process of cropping it to remove any unnecessary elements and focus on the desired subject. This can be done digitally or with scissors and a ruler. Cropping a photo can help to create a more aesthetically pleasing composition, as well as draw attention to the main subject. It can also be used to remove unwanted elements from a photo, such as people in the background or objects that are distracting. Clipping a photo is an important step in the editing process for many photographers.
