Just stepped down from 4x5 and have already purchased a RB67. I know this question has been asked a lot of times by now, but I just have a few more questions to clear up any confusion that I have...
1. From what I read, 10 shots of 6x7 will only fit on a 8.5x10 paper?
2. For filing negs in plastic sleeve, I read that you cut the negs into 3 strips of 3 and use extra wide filing pages? If so, then I will get 3 strips of 3 and 1 strip of 1?
3. I was thinking about just wasting the first frame on purpose so I only get 9 shots and they will fit perfectly on a 8x10 and those sideways filing pages. What would you say about this?
I have a GF670 folder camera that makes both 6x6 and 6x7 formats. For the 6x7s I cut them 3-3-2-2 and store them in the PrintFile Style No. 120-4UB plastic pages. This page will hold 12 6x7s, so two spaces are unused.
For proofing I use Ilford MGIV 8½x11 RC Deluxe paper. Everything fits nicely for me. You can use 8x10 paper, but it's really crowded, with frames usually truncated.
I cut my negatives 3-3-3-1. The three columns of 3 negatives go in a standard print file holder to print on 8x10. I put the remaining negative in a print file that holds nine single negatives and prints on 8x10. When I file, every tenth page is the page with nine individual negatives.
I've used all the approaches suggested above. As a starting point, try Ken's second idea (8½ × 11 paper); with care, enough of the tenth frame to be useful can be included. I've been using the Ilford 8½ X 11 paper for all my contacting, regardless of the format, since it makes negative strip placement quicker and simpler.
