Darkroom Film Processing
If you plan on developing your own film, you need to understand the process and master each step. A perfectly taken photo isn't much use if it isn't developed properly. There are more steps in color developing and the time and temperature requirements are different. Film developing basically involves converting the light-sensitive material (film or paper) which has been affected by light to black metallic silver. This develops a visible image from the invisible image. The exposed film is brought into contact with a solution containing a developing agent. This is called chemical or direct development.
Another seldom and more difficult process is called physical development, where you develop the image from a soluble silver salt contained in the solution itself. There are various formulas used as developing agents and most possess the following essential ingredients: developing agent, preservative, accelerator or activator, and restrainer. When your image is visible, you must fix, wash and dry the print. There are various time limits on developing procedures and you will need to learn them properly. It may sound complicated, but it's an easy procedure if taught correctly.
