| Question | Answer |
| What is Synergism? | is the actions of 2 agents working together is greater then the sum of each agent working independently. |
| What are the 2 developer and reducing agents? | Phenidone and Hydroquinone. |
| What does the preservative protect? | the hydroquinone from both aerial and internal oxidation. |
| What does the hardener do? | it controls emulsion swelling and stickiness so the film doesnt stick to the rollers. |
| What is the solution temperature? | developer should be 68-72 degrees F, automatic is 85-105 degrees F. |
| What is solution conentration? | percentage of water versus other chemicals in the sloution. Measured by specfic gravity. |
| Solution pH | 10-11.5 and should not vary more than +/- 0.1 |
| 5 factors of developer activity | soultion temperature, immersion time, solution concentration, type of chemicals used, solution pH |
| What do fixer solutions do? | remove all of the unexposed and undeveloped silver halide crystals from the film; image cleared |
