I have several films (135 and 120) that were developed at too low contrast. They need grade 4 at least, leaving little room for manipulation. The reason(s) why they turned out too low contrast is not the topic. I have ordered the chemicals to prepare chromium intensifier. The issue is that the films have already been cut in strips for storage. I intend to insert them in reels for intensification processing. First question is about drying. Either dry each strip, hanging from one corner (I have some mini-clips with just one tooth) with a second clip pulling from the opposite corner. Fairly easy with 135 (perforations); a little tricky with 120. Once dry, put away to flatten for a few days. Alternate method is to dry them while still on reels. Positive: no tricky manipulations, controlled curl, only lengthwise. Negative: risk of drying marks or worse, gelatin adhering to the reel, especially with 120, where the image edge is close to the film edge. Advice from members with actual experience is welcome. Second question. I need to gain the equivalent of 1 to 1.5 paper grade. I see that the amount of HCl in the working strength bleaching solution can be between 2.5 and 12.5cc for 1000cc. With the lesser amount giving more intensification. Could someone provide a starting point, in view of my goal of 1-1.5 paper grade intensification? Of course I'll use non-keeper frames for preliminary tests, but some indication would be welcome. Third question. I have read that re-development should be with a developer with low sulfite content, with Dektol 1+3 suggested. I'm also concerned about grain if re-deloping in Dektol. In view of these concerns, is there any advantage in preparing a custom developer with even less sulfite? Say, take D-76 and decrease sulfite to, say, 50g, or whatever? Thank you.
