Now that your film is loaded, you can bring it out of the darkroom or bag. At this time you will follow the directions provided with your chemicals.

The general directions for Diafine are: Three minutes in part A with agitation for ten seconds each minute. Drain part A back into container A. Repeat steps above with Part B.

21

Rinse and then fix according to the directions. Rinse well and finish with a light wash of Photo-Flo. Hang negatives to dry in a DUST FREE place. Clothes pins work very well.

I use the plastic agitation rod during the developing process. Some people prefer to invert the tank. Experiment to see what works best for you!
