Time and temperature: So how do you tell when development is complete if you have to do everything in the dark? The film needs to be in the developer at a particular temperature (usually 68F) for a certain amount of time. You can vary these i.e.
Time and temperature. Many factors must be considered if you want to ensure correct development during film processing. Two of these factors are the length of time the film is allowed to develop and the temperature of the developer solution.
To make a dark slide, simply make a separate exposure made at the same ISO, exposure time and temperature as the image you intend to use it with. Exposure of what? Darkness. Leave your lens cap on.
Each of these baths is closely monitored and maintained at a specific temperature and treatment time. Developer baths are most sensitive to deviations from the standard processing conditions (e.g., time and temperature); ...
