If developer temperature is too high during processing, which film outcome is most likely?

• A. Expired fixer solution
• B. Cold wash water
• C. Development time too short
• D. Development temperature too high

Answer: (D)

Development rate follows temperature. When the developer is hotter than recommended, the chemical reactions occur more quickly, so the latent image is converted to silver faster and the film becomes overdeveloped. The result is a darker image with higher density and greater contrast than intended. The other scenarios affect different parts of processing: expired fixer influences fixing, not development; cold wash water mainly affects washing steps and can slow or halt development-related processes but doesn’t cause overdevelopment by itself; development time too short would produce underdeveloped film, not overdeveloped.
