Image editing encompasses the processes of altering
images, whether they are
digital photographs, traditional
photochemical photographs, or
illustrations. Traditional analog image editing is known as
photo retouching, using tools such as an
airbrush to modify photographs, or editing illustrations with any traditional
art medium.
Graphic software programs, which can be broadly grouped into
vector graphics editors,
raster graphics editors, and
3D modelers, are the primary tools with which a user may manipulate, enhance, and transform images. Many image editing programs are also used to
render or create
computer art from scratch.
