I'm having serious trouble loading 120 film to Patterson reel in recent days. I'm using a 27' Adorama changing bag to load the film. I can load 135 film with absolutely no trouble inside the changing bag but have been quite unsuccessful with 120 film. Either I fail to slide the film into the groves properly or even after sliding the film past the ball bearing, I'm not able to load the rest of the film. Ironically, I'm always successful in loading 120 film outside the dark bag with my eyes closed! Tony Evans suggested an interesting trick: "I cut a piece of thin Mylar the width of the film and about 10 cms long and insert it (in daylight) through past the ball-bearings leaving about 2-3 cms sticking out from the feeder end.. In the dark (my changing bag) I can press the taped end of the film flat across the projecting mylar and push it though. Once in, just pull the mylar out from the ball-bearing end and proceed to load.." I tried this method both inside and outside the changing bag but couldn't get it working. The tape gets stuck at the ball bearing. Chuck Foreman shared his process for loading: "I sply my left fingers to feel the nubs of the starting plastic channels., then with my right hand/fingers load the lower film corner and uncurl or feel for the upper corner and place it in the reel channel accordingly. I then switch hands ie with my left and feel if the film is properly spread and in the slots. I may even pull it a bit more onto the reel, then I start the left/right twisting to begin taking up the film. etc. If it's loaded then this step usually works and you need merely to tear or gently remove the masking tape from the backing paper. " This is nearly the same process as mine. [Thanks Tony and Chuck - you guys are very kind and helpful.] In the initial days when I was shooting Arista Edu 400 in 120, I had nearly no trouble. But of late I've been shooting Tri-X and FP4+ and not having a good time with these. Now I'm wondering what I should do to solve my problem. Converting my bathroom into a darkroom might solve the problem as I am able to load outside closing bag with my eyes closed. But I'm hesitant to take that step at the moment and hence looking for alternative solutions. Will switching to steel reels help? And can steel reels be used with Patterson tank? Or should I look at larger sized changing bag?
