1.Developing tank is a developing tank is a light-tight container used for developing film. A developing tank allows photographic film to be developed in a daylight environment

2.Contact print is a photographic image produced from film; sometimes from a film negative, and sometimes from a film positive or paper negative.

3.Developer is one or more chemicals that convert the latent image to a visible image

4.A darkroom is used to process photographic film, to make prints and to carry out other associated tasks. It is a room that can be made completely dark to allow the processing of the light-sensitive photographic materials, including film and photographic paper.

5.Stop bath is a chemical bath usually used in processing traditional black-and-white photographic films, plates, and paper used after the material has finished developing.

6.Enlarger is a specialized transparency projector used to produce photographic prints from film or glass negatives, or from transparencies.

7.Johann Heinrich Schulze proved that the darkening of silver salts, a phenomenon known since the 16th century and possibly earlier, was caused by light and not heat
