Processing Black and White Film.

"Processing film for developing black and white film will vary from different processing chemicals for black and white film photography, but it largely remains the same. Black and white film requires a constant temperature, but is much more flexible than color print film during the C-41 process or color reversal film during the E-6 process. Additionally, water temperature does not need to be kept as warm as the color film types, as the ideal temperature is around 20-22°C instead of 37°C – making black and white film development a simpler process. However, different black and white film types have different development times and different film speeds have different development times."
