Preparation of AGFA developer (2)

developer used

development time

development temperature 20 ° c/68 ° F. Generally speaking, the normal contrast is developed for 12 minutes

diluting and developing time

diluting the storage solution to produce working solution, and the developing time changes according to the need of contrast control and the speed of developing film

the following dilution and development time is only used as the reference time. The final specific dilution and development time depends on the mixing in the dark room and the required contrast
