Landscape - Developing

The first image shows the three tanks where the developer, stop and fixer is. To begin with you place the images individually in frames and then hang them up on to a cage (second image). You do this in pitch black so no light gets on to the film and ruins the images. The first chemical you use is the developer which you place your images in for 15 minutes, gauging on the temperature being 21 degrees. You agitate for the first minute non stop, dipping the cage up and down in the developer and then for ten seconds every minute. Once this is done you place your film in the second tank which is the stop, this does just that, stops the developer from working on your images. You place your film in this tank for thirty seconds and constantly agitate. Finally you put the cage in the third and last tank, which is the fixer, for five minutes with constant agitation again. This allows your image to stay on the film. Once all three tanks have been used it is okay for the film to be out in to the light where you put the film to wash for 20 minutes and then finally dry.
Fixer;"Photographic fixer is a mix of chemicals used in the final step in the photographic processing of film or paper. The fixer stabilises the image, removing the unexposedsilver halide remaining on the photographic film or photographic paper, leaving behind the reduced metallic silver that forms the image, making it insensitive to further action by light. Without fixing, the remaining silver halide would quickly darken and cause fogging of the image. The most common salts used are sodium thiosulfate—commonly called hypo—and ammonium thiosulfate—commonly used in modern rapid fixer formulae."
