Darkroom manipulation is a traditional method of manipulating photographs without the use of computers. Some of the common techniques for darkroom manipulation are dodging, burning , and masking , which though similar conceptually to digital manipulations, involve physical rather than virtual techniques.
Burning: a darkroom technique. To burn-in a print, the print is first given normal exposure. Next, extra exposure is given to the area or areas that need to be darkened. A card or other opaque object is held between the enlarger lens and the photographic paper in such a way as to allow light to fall only on the portion of the scene to be darkened.
A prospective campground must meet certain standards before being considered as a potential Jellystone Park location. Each campground is required to have a minimum of 100 campsites and 4 full-service cabins, a commercial swimming pool that is at least 20 feet by 50 feet, first class restroom facilities, a laundry facility and a retail store.
For example, Ansel Adams used darkroom exposure techniques to darken and lighten photographs. Other techniques include retouching using ink or paint, airbrushing, double exposure, piecing photos or negatives together in the darkroom, and scratching instant films. Software for digital image manipulation ranges from casual to professional skillsets.
A darkroom is used to process photographic film, make prints and carry out other associated tasks. It is a room that can be made completely dark to allow the processing of light -sensitive photographic materials, including film and photographic paper .
Other object manipulation skills are linked to sport, magic, and everyday objects or practices. Many object manipulation skills use special props made for that purpose: examples include the varied circus props such as balls , clubs , hoops , rings , poi , staff, and devil sticks ; magic props such as cards and coins; sports equipment such as ...

The Zone System is a photographic technique for determining optimal film exposure and development, formulated by Ansel Adams and Fred Archer. [1] Adams described the Zone System as "[...] not an invention of mine; it is a codification of the principles of sensitometry, worked out by Fred Archer and myself at the Art Center School in Los Angeles, around 1939–40."
