"Under the safelight, remove the exposed film from the camera and place it in the developer tray. Gently rock the tray so that a wave of developer washes back and forth across the film. When it looks dark enough, pick the film up by one corner and let it drip for a few seconds. Then place it in the second tray, the stop bath (or water, if so desired.)
Again, rock the stop bath tray for about ten seconds (this is called "agitating"), lift up the negative and let it drip, then place it in the fixer tray. Agitate the fixer tray for at least two minutes. Fixing the image is very important: the fixer dissolves out any silver which hasn't turned black, so that years from now, the picture won't turn yellow or some other unwanted color. Sometimes improperly fixed photographs just fade out, as if they were bleached by time. After a minute of agitated fixing, it is OK to turn on the room light--after first checking to see that the photographic paper is covered!
The last "wet" processing step is to wash the photographic paper in clean, room temperature water for about four minutes. This step is very important, too, because if any fixer is left in the paper, it will act like a bleach and cause the photographic image to fade over time. Room temperature water is important because water which is too hot or too cold can damage the layers which make up the photographic paper. Last, pat the paper dry with paper towels or with a clean cloth towel and set the paper on a clean space where it will quickly dry."
