I am doing a project on the Processing of Black and White film, but need some steps to show how it works could you help me before the end of the week.

Check the processing and printing link on the first page of this site. Check out a set of the Ansel Adams books. Check the Stroebl book.

Tamara: I will give you the steps in basic form. Please understand that each photographer tailors developing to his or her individual preferences depending upon factors such as type of enlarger, amount of contrast wanted, etc. The following is for the development of 35mm roll film.
Step 1. Set out the following equipment and chemicals: a light-tight developing tank, developing reel, a bottle opener, a timer or clock, and enough each of film developer, water, fixer and Photoflo solution to fill the developing tank.
Step 2. In a completely dark and light-tight room, such as a darkroom, closet or bathroom, use the bottle opener to remove the end cap from the film cassette. Remove the film and cut off the leading end that is tapered. Load the film onto the reel, place the reel in the developing tank, and put on the lid tightly. Turn on the light.
Step 3.Fill the tank with tap water and dump several times to pre-wet the film. Look up the time and temperature for processing either on the film box (usually inside the box) or on the developing chemical sheet. The temperature of the developer should be from about 68 to 75 degrees. The time will vary according to temperature. Most developing times are around 7 minutes at 68 degrees.
Step 4. Fill the tank and start the timer or note the time on the clock. Invert the tank back and forth for about 30 seconds. Let it sit for 30 seconds and invert it again back and forth for about 5 seconds. Do this at 30 second intervals until the developing time is expired.
Step 5. Drain the developing tank and rinse by filling the tank with water a couple of times and draining.
Step 6. Pour fixer into the tank and agitate by inversion of the tank as with the developer. This step takes about 5 minutes. At the end of five minutes, remove the lid from the tank, pour out the fixer and wash the film by running water into the tank under a tap for 15 minutes. Dump the tank every 4-5 minutes to remove fixer that has settled to the bottom of the tank.
Step 7. Remove the reel from the wash water, dip the film into the Photoflo solution for about 30 seconds and then hang the film up to dry. Use a clothes pin to hang the film with and put one on the bottom of the roll to prevent the film from curling. That's it. Hope this helps, Doug.
