Hi!
I processed a batch of HiCon in D19 this weekend, easiest process ever.
I used a safelight, and three buckets (dev, wash, fix)
1. D19, 5 min or until I could see images, It seems you cant overprocess it, couldn't get more density by incrasing the time (so this is not a film to push)
2. Wash about 2min (you could use stop bath, but water is free)
3. Fix for 5 min
(then wash it again, and let it dry...)
have fun
