Does anybody have any development times for push processing Kentmere 100 ISO film 3-stops (to 800 ISO) in D-76. According to the Kentmere data sheet, if I want to push the film 1-stop to 200, I should increase the development time from 11.5 minutes to 15.5 minutes. This seems like a big jump for only 1-stop! If I want to push it 3-stops am I looking at a 20+ min dev time? Any info on this would be appreciated! A quick search didn't turn up much on kentmere films, and it seems that a lot of people didn't even know that kentmere made films! Thanks!
