Colin, that's a worthwhile question. This negative had light leak problems on both ends, plus some rather harsh shadows on one end. I was not happy with the neg as a whole. But I found that two or three good 4x5 negs can be taken out of a useless 7x17. Plus, I can enlarge and get the larger prints. People like large for some reason these days. I don't agree with that desire, but large attracts more attention and sales.
Alex while I like the result I think that it could be improved by increasing the gap between the photo's. As it is the photo on the RHS appears to be have been taken further away. The increase in the gap will give each photo more room to breath and the viewer has to work harder to join them together.
