DADA or push process is done with 400 speed film with ASA set at 1600 then it is developed with 300 ml Polymax and 300 ml water for 9 min at 68 degrees f. 9 min constant agitation. Fix as usual of for longer and permawash normally. I have had excelent results with this process and it is inhanced by using fiberpaper(matte) in which you can color on with color pencils.(posted 9554 days ago)
