Digital image editing is the process of altering digital images, whether they are digital photographs or other types of digitally represented images. Specialised software programs called vector graphics editors or bitmap graphics editors are the primary tools with which a user may manipulate, enhance, and transform images. These editors are capable of editing images in many diverse ways (Wikipedia, 2006). In graphics design, image editing (composition) has been used to realistically blend old images into new better ones. The goal of image editing is to combine objects or regions from various still photographs to create a seamless, believable, image or image sequence which appears convincing and real.

Editing images digitally is a good way to produce better quality images in general, since it is fairly easy to do. With image composition tools, if one portion of the image needs alteration, the whole image does not need to be regenerated.
