| Fixer | Chemical used to preserve the developed image |
| Gelatin | a virtually colorless and tasteless water-soluble protein prepared from collagen and used in food preparation and in photographic processing |
| Developer | A solution used to make visible the image produced by allowing light to fall on the light-sensitive material. |
| Inverted | put in the opposite position or turned inside out |
| Shutter Speed | the speed that you set the camera shutter to open and close again |
| Aperture | Lens opening. The hole or opening formed by the metal leaf diaphragm inside the lens or the opening in a camera lens through which light passes to expose the film. |
| Latent | existing but not yet developed |
| Depth of Field | The amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph. |
| Stop Bath | An acid rinse used as a second step when developing black-and-white film or paper. It stops development and makes the hypo (fixing bath) last longer. |
| Contact Print | A photographic print made by exposing the negative in contact with the photo paper |
| ASA or ISO | the film speed number |
| Diaphragm | A mechanical device that stops down to create various size apertures |
| Emulsion | Micro-thin layers of gelatin on film in which light-sensitive ingredients are suspended. |
| Silver Halide | light sensitive material that is part of photo-emulsion |
| F- numbers | The scale that the aperture settings are counted |
