Photo editing or image editing is the changing of images.[1] These images can be digital photographs, illustrations, prints, or photographs on film). Traditional editing, such as airbrushing, is done by hand. Now photo editing is done by programs such as Photoshop, Gimp and Microsoft Paint.
Photo editing is done for many reasons. Many photos of models are edited to remove blemishes or make the model "better". This is usually called retouching, airbrushing or Photoshopping, even if Photoshop or airbrushes are not used. Other reasons to edit a photo include fixing errors (red eye, contrast, brightness, etc.), practical jokes, and to trick people. Photo editing is also used to make completely new images. Photo editing is sometimes called photo manipulation, a term which sounds negative.
