I have not run any Ilford film to date as reversal, don't have much of it. I have run Foma negative and reversal, Shanghai GP3, Orwo UN54, Silvermax and Kodak Tri-X reversal as well as Kodak colour Vision2 cine neg film. The Silvermax and colour negative film needs longer developing times than the other films, so I do not dilute the developer and run for the same times as below.
I shoot all my film at box speed, but the colour neg at 1 stop under.
I cannot give a time for multi grade developer, but my times for D19 dilute stock 1:1 at 23degC which I am using right now with Foma R100 both 35mm and 16mm.
Dev 1- 3min 30 const agitation
bleach - 60 sec const agitation
clearing bath - 60sec const agitation
wash and open tank to dark room lighting 2x 75W globes for 2 to 5 mins
Dev 2- 90 to 120 sec. Same developer as Dev 1
Fixer - 2 mins
I have run many test strips of bracketed film, and I do this for each new developer or when I store mixed developer for more than a fortnight just to confirm my times.
Trust this helps.
