Which of the following are TRUE regarding daily checking processor developer solution temperature?

• A. 1 and 2
• B. 1 and 3
• C. 2 and 3
• D. 1, 2, and 3

Answer: (C)

Temperature of the developer solution directly controls how fast or slow the film is developed, which in turn affects image density and contrast. Daily checks are needed to catch any drift away from the target range so results stay consistent. The two true points are that you must monitor the temperature regularly and that you adjust the development time if the temperature is off, to compensate and keep the final image quality stable. In practice, you’d record the temperature, ensure the tank is brought to the correct range, and modify the processing time if deviations occur. This ensures consistent results from day to day. Claims that temperature doesn’t matter or that daily checks aren’t needed aren’t aligned with sound QC and processing practices.
