| grain | the pebble-like appearance of the silver that becomes more evident when the image is enlarged. |
| ISO | a number that describes a film's relative sensitivity to light (i.e. how quickly an image will form). |
| ISO 100 | called slow film, needs more light to form an image, tiny grain, good for fine details |
| ISO 400 | called fast film, needs less light to form an image, bigger grain, good for low light or fast action |
| Undeveloped film must be handled in ... | total darkness - a changing bag or a closet that locks out the light. |
| Undeveloped film is wound onto a film reel so that ... | chemicals can reach all parts of both sides of the film for the entire length of the film. |
| After winding undeveloped film onto a reel, the reel is placed in ___ _________ _____________ _____ for the chemical processing steps. | a daylight developing tank |
| A latent image is one that... | has been produced by the action of light energy but is not yet visible. |
| The function of developer is to ... | produce a chemical action (reduction) that makes a latent image visible. |
| The function of fixer is to ... | stop the chemical action of the developer (stop any more of the silver from turning black), and remove the film backing. |
| The function of hypo-clearing agent is to ... | remove chemicals from the surface of the film so that the final wash time can be shortened. |
| The purpose of the final wash is to ... | remove any remaining trace of chemicals from the film surface so that no stains will appear at a later time. |
| The purpose of Photo-Flo is to ... | prevent water spots from forming on the surface of the film. |
| Developer is not usually used full strength; it is usually diluted 1\:1. This means ... | a measured amount of developer is mixed with an equal measurement of water. |
| The length of time for the developer step depends on ... | the temperature of the developing solution. |
| This word means to move the film around during the developing process so that fresh chemicals can reach the surfaces of the film. | agitation |
| During the chemical developing process it is safe to expose film to light AFTER which step? | the fixer step |
| developer | will cause dark stains |
| fixer | may cause bleach stains |
