Which statement correctly identifies the monthly QA parameter two for film processing?

• A. Film fixer retention and dark room conditions
• B. Film fixer retention and film and chemical storage
• C. Dark room conditions and film and chemical storage
• D. All three

Answer: (C)

Monthly QA parameter two for film processing focuses on environmental and storage controls that protect film quality. The dark room must meet safe lighting standards to prevent fogging or unintended exposure of unprocessed film, and the storage of film and processing chemicals must be proper to avoid chemical contamination, degradation, or exposure to heat, humidity, or fumes. These factors directly influence how consistently films develop over time, making them appropriate for a monthly check that ensures the processing environment and storage practices remain reliable. The other options involve fixer-related concerns or combinations that don’t address the environmental and storage conditions that this parameter emphasizes.
