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 .
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.
Fixation is commonly achieved by treating the film or paper with a solution of thiosulfate salt. Popular salts are sodium thiosulfate—commonly called hypo—and ammonium thiosulfate—commonly used in modern rapid fixer formulae. [1]
Special equipment was needed to process Kodachrome. Since 2010, there has been no commercial entity that processes Kodachrome anywhere in the world. In colour print development the Ilfochrome, or Cibachrome , process uses a print material with the dye-stuffs present and which are bleached out in appropriate places during developing.

Such measurements enable the photographer to choose the right photo paper and the correct exposure, obviating experiments with test strips. Once the papers and darkroom have been calibrated, the first print from a previously measured negative is a success at once.
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.
