Abstract
A method and system for environmental control in film processing is disclosed. In general, photographic film is coated with a processing solution, such as a developer solution, and is then developed within a controlled air environment. In the preferred embodiments, the temperature and humidity within the air environment is strictly controlled, which allows the development process to be more accurately and consistently controlled. This also allows fewer processing chemicals to be used and reduces harmful effluents caused by photographic film processing.
