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.
Dodging: also a darkroom technique. A card or other opaque object is held between the enlarger lens and the photographic paper in such a way as to block light from the portion of the scene to be lightened. Since the technique is used with a negative-to-positive process, reducing the amount of light results in a lighter image.
The wet collodion photography process, used at the time, required that the image be developed while the plate was still wet, creating the need for portable darkrooms such as this one. In most darkrooms, an enlarger , an optical apparatus similar to a slide projector, that projects light through the image of a negative onto a base, finely ...
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.
This category contains categories and articles relating to the theory and methodology of composing and/or taking photographs, or to their manipulation during or after processing.
The Sabatier effect, also known as pseudo-solarization (or pseudo-solarisation) and erroneously referred to as the Sabattier effect, is a phenomenon in photography in which the image recorded on a negative or on a photographic print is wholly or partially reversed in tone. Dark areas appear light or light areas appear dark.
The website's primary subject is analog photography that involves using film and darkroom techniques to produce negatives, slides or prints. Subjects discussed in the forums are concerned with aspects of traditional photography, including processes like cyanotype, platinum printing and other alternative processes. Each subject area has a forum.
A chemogram (from "chemistry", "optic" and gramma, Greek for "things written") [1] is an experimental art where a photographic image is partly or fully enlarged and processed onto photographic paper in the darkroom and afterwards selectively painted over in full light with chemicals used in photographic processing.
