Photograph manipulation involves the of a photograph. Some photograph manipulations are considered to be skillful artwork, while others are considered to be unethical practices, especially when used to deceive. Photographs may be manipulated for political propaganda, to improve the appearance of a subject, for entertainment, or as humor.
Depending on the application and intent, some photograph manipulations are considered an art form because they involve creation of unique images and in some instances, signature expressions of art by photographic artists. For example, Ansel Adams used darkroom exposure techniques, burning (darkening) and dodging (lightening) a photograph. Other techniques include retouching using ink or paint, airbrushing, double exposure, piecing photos or negatives together in the darkroom, and scratching instant films. Software tools applied to digital images range from professional applications to basic imaging software for casual users. Photoshopping is a verb for photograph manipulation as a genericized trademark of Adobe Photoshop.
Photo manipulation dates back to some of the earliest photographs captured on glass and tin plates during the 19th century. The practice began not long after the creation of the first photograph (1825) by Joseph Nicéphore Niépce who developed heliography and made the first photographic print from a photoengraved printing plate. Traditional photographic prints can be altered using various methods and techniques that involve manipulation directly to the print, such as retouching with ink, paint, airbrushing, or scratching Polaroids during developing (Polaroid art). Negatives can be manipulated while still in the camera using double-exposure techniques, or in the darkroom by piecing photos or negatives together. Some darkroom manipulations involved techniques such as bleaching to artfully lighten or totally wash out parts of the photograph, hand coloring for aesthetic purposes, or mimicking a fine art painting.

Image editing encompasses the processes of altering s, whether they are digital photographs, traditional photo-chemical 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.
Digital photography uses cameras containing arrays of electronic photodetectors interfaced to an analog-to-digital converter (ADC) to produce s focused by a lens, as opposed to an exposure on photographic film. The digitized image is stored as a ready for further digital processing, viewing, electronic publishing, or digital printing. It is a form of digital imaging based on gathering visible light (or for scientific instruments, light in various ranges of the electromagnetic spectrum).
A photograph (also known as a photo, image, or picture) is an created by light falling on a photosensitive surface, usually photographic film or an electronic , such as a CCD or a CMOS chip. Most photographs are now created using a smartphone or camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography.
