Image editing encompasses the processes of altering images, whether they are digital photographs, traditional analogue photographs, or illustrations. Traditional analogue image editing is known as photo retouching, using tools such as an airbrush to modify photographs or editing illustrations with any traditional art medium.
There are two basic ways that images can be adjusted. Pixel editing works at the pixel level and requires altering the original image. Parametric Image Editing works by saving instruction sets that change the appearance of images without actually changing the original image data.
