    • A. During development
    • B. During fixing
    • C. During washing
    • D. During drying
    • A. During development
  1. What are the steps for processing?

    C. Developing, fixing, washing, drying
  2. Which of the following doesnt exist in what development consists of?

    D. Wheels
  3. What does reducing agents do?

    D. Provide free electrons to silver ions
  4. What are the two reducing agents?

    D. Phenidone and hydroquinone
  5. What does the reducing agent phenidone do very well?

    D. Works quickly to produce shades of gray
  6. What does the reudcing agent hydroquinone do well?

    B. Works slowly to produce black areas
  7. True or false: reducing agents are used for developers to become oxidized.
  8. True or false: If reducers are not properly replenished, it chanes to deep amber -> brown -> rust red
  9. What typically is used as an activator?

    C. Sodium carbonate
  10. What does activators do to the pH balance?

    D. They keep it maintained.
  11. What does activators do for the penetration of reducing agents?

    A. Swells gelatin making it easier to penetrate
  12. What typically are restrainerse and what do they do?

    B. And D.
  13. True or false: Preservatives are typically sodium sulfite and decreases oxidation made by air.
  14. What is the hardener responsible for?

    D. All of the above
  15. True or False: If there arent high enough levels of hardener, gelatin on the developer will stick to rollers, if too much hardener then it may harden emulsion too soon.
    A. True
  16. Water should be filtere with...

    D. 5-10 micrometer
  17. What does fixing do to undeveloped silver halides?

    B. Removes it
  18. What does the "fixing" stage have differently than the "developing" stage?

    A. Fixing has clearing agents while deveoloping has reducing agents.
  19. What does the clearing agent in the "fixing" stage do?

    A. Bonds with unexposed silver halides becoming thiosilver sulfate.
  20. What does activator in the "fixing" stage do?

    B. And C.
  21. In the "fixing stage" what does preservatives do?

    A. Removes silver from ammonium thiosilversulfate to allow ammonium thiosulfate to continue to remove silver halides
  22. True or False: The hardener for the "fixing" stage does something completely different than the "developers" stage.
    True: The hardener does the exact same thing the stage for developing.
  23. The solvent for both developing and fixing stages are...

    C. Filtered and treated water.
  24. What should the temperature be for the developer for reduing agents to work optimally?

    D. 90-96 degrees fareneit.
  25. True or False:if fixer is not washed off from the film, film will yellow and brown in age.
  26. What humidity and temperature are used for storage of films?

    C. 70 degrees with 60% humidity
  27. Transport racks have three series of rollers that...

    B. Provide constant tension to move film through each tnak.
  28. Transport racks have three turn around equipment at the bottom of the tank. These are...

    B. Master roller, plantery rollers and guide shoes
  29. It is known that cross over networks have a similar turnaround equipment in transport racks. A misaligned guide roller can..

    A. Scratch the film
  30. What does the drive system do?

    A. Turns the whole system
  31. How does the dryer system dry the films?

    E. Both C and D.
  32. For the replenishment system, how much water does it squirt from developer/fixer

    B. 4-5ml/6-8ml
