Image editing encompasses the processes of altering images, whether they be digital photographs, traditional analog photographs, or illustrations. wikipedia.org

Digital photography uses an array of electronic photodetectors to capture the image focused by the lens, as opposed to an exposure on photographic film. The captured image is then digitized and stored as a computer file ready for digital processing, viewing, digital publishing or printing. wikipedia.org

Photo manipulation is the application of image editing techniques to photographs in order to create an illusion or deception (in contrast to mere enhancement or correction), through analog or digital means. wikipedia.org

Compositing is the combining of visual elements from separate sources into single images, often to create the illusion that all those elements are parts of the same scene. Live-action shooting for compositing is variously called "chroma key", "blue screen", "green screen" and other names. wikipedia.org

Commercial photography is any photography for which the photographer is paid for images rather than works of art.
