Ok, I've tried two discs of fil (Process C-41a) in D-76, and neither has come out. The first was exposed to my safelight (duhhh), the second was opened in complete darkness, developed 12 minutes at 21ºc (this worked well with new color stock), wash, fixed for 8mins. The negatives came out completely black. I want to try it with another roll, and ideas as to times??
