How do you make a photogram?Firstly you choose a series of objects. You arrange these objects on a piece of light sensitive photographic paper. This is then exposed to light for a few seconds. The paper is then taken over to the wet area of the darkroom and soaked in a series of chemicals.
The main chemicals used in the darkroom are developer, which causes the silver iodide of the paper emulsion to darken if it has been exposed to light, and fixer, which removes the undeveloped silver iodide from the emulsion. A chemical used to completely stop the development process is called stop bath, and is used between the developer stage and the fixer stage.
