Which item is required for automatic processing but is not listed as a manual processing item?

• A. The temperature of film processing chemicals must be appropriate for the type of film.
• B. The darkroom must be light-tight to the dark-adapted eye.
• C. Documentation to show when film processing chemicals are changed.
• D. If a safelight is used, it needs to be adequate for the film speed.

Answer: (A)

Temperature control of processing chemicals is crucial for consistent film development, especially when using automatic processors. Automatic systems rely on a preset, precise chemical temperature to achieve reliable densities and contrast, and they are designed to maintain that temperature automatically. Therefore, ensuring the chemical bath is at the correct temperature is a requirement particular to automatic processing because the machine handles it for you. In manual processing, the emphasis is on the operator’s control of time, agitation, and handling conditions, with other items like keeping a light-tight darkroom, documenting chemical changes, and ensuring safelight compatibility covering different manual practices. The other options reflect manual-processing considerations more than automatic-processing requirements, which is why the temperature item stands out as the best choice for automatic processing.
