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 .
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.
Electronic Timer-Analyzer. A photo-lab timer, photo interval timer, or darkroom timer is a timer used in photography for timing the process of projecting negatives to photosensitive paper with an enlarger, making photographic prints of them at any scale.
In the RA-4 process, the bleach and fix are combined. This is optional, and reduces the number of processing steps. [12] Transparency films, except Kodachrome, are developed using the E-6 process, which has the following stages: A black and white developer develops the silver in each image layer. Development is stopped with a rinse or a stop bath.
Unsharp masking (USM) is an image sharpening technique, first implemented in darkroom photography, but now commonly used in digital image processing software. Its name derives from the fact that the technique uses a blurred, or "unsharp", negative image to create a mask of the original image. The unsharp mask is then combined with the original ...
1. Chocolate Fondue. Think of that fondue fountain at the buffet as Willy Wonka's sacred chocolate waterfall and river. The chocolate must go untouched by human hands, or it will be ruined.
Stop bath accounts for the vinegar-like odor of the darkroom. In its concentrated form it can cause chemical burns , but is harmless when diluted to a working solution. Stop bath becomes exhausted when carried over developer causes the solution to become alkaline.
