Questions and Answers

What should be done if the surface of the appearance solution becomes oxidized?

  • Cover the basin completely to prevent further oxidation.
  • Stir the solution continuously to blend the oxidized material.
  • Add more solution A to neutralize oxidation.
  • Dispose of the oxidizing materials using an airflow sheet. (correct)

What is the maximum allowable time for the processing of the image?

  • 7 minutes
  • 6 minutes
  • 5 minutes (correct)
  • 8 minutes

How does an increase in temperature affect the appearance time of the solution?

  • It has no effect on the appearance time.
  • It decreases the appearance time by 1/4 minute for each degree. (correct)
  • It doubles the appearance time for every degree increase.
  • It increases the appearance time by 1/4 minute for each degree.

Flashcards

Acid Synthesis

The process of mixing chemicals and water to create film developing solutions, like developer and fixer.

Basin or Enlarger

A container used to prepare developing solution for photographic film.

Appearance Time and Temperature

The duration of the developing process, the time film stays in the developing solution, is affected by solution temperature.

Washing the Acidification Device

The process of cleaning the developing equipment after use to prevent contamination and ensure optimal performance.

Study Notes

Darkroom Procedure

  • The installer or fixer consists of two parts (a) and (b). Part (a) holds 5 liters, and part (b) holds about a liter.
  • A basin, or enlarger of 20 liters or more is needed.
  • A tool to move fluids.

Acid Synthesis Method

  • Put 13 liters of water in the basin or enlarger, then add solution A slowly, with constant stirring.
  • Then add solution B to the water, with stirring.

Notes

  • In the past, the processing materials were in powder form that dissolved in water.
  • When changing the appearance of the acid, companies stopped them leaking.
  • It is preferable to wash the acidification device with the pulleys at each change of solution.
  • Always cover the solution.
  • On case of oxidized surface, the oxidizing materials can be disposed by using a sheet of airflow pass on the surface of the solution.
  • The time of appearance is seven times the time necessary for the process.
  • The ideal temperature is 20°C and the maximum time of appearance decreases 1/4 minutes and vice versa.
