Peter, I use Canon F-1 cameras, which wind the film over the sproket take-up spool. With this design, I never have any problem loading film emulsion side in on developing reels.(posted 8216 days ago)However, I also have an AE-1 that I often loan out to friends. This camera winds the film under the take-up spool. Often, with this camera, film is left in the camera for several weeks. When I try to wind this film on SS reels, it is a major annoyance. After a week or more bent backwards on the take-up spool, the film will not lay correctly, emulsion side inward, on the developing reel. On occasion, when it has been particularly balky, I've simply wound the film on emulsion out. I was uncomfortable about doing it, but really didn't have a choice. I finally accepted that I'd have destroyed the film trying to force it on the reel in the standard orientation.
Obviously, the film is more vulnerable to scratches with the emulsion out. Although this made me uneasy, I have not seen any problem with it. Perhaps I have been lucky. In any case, it worked and I have since done it whenever I've encountered that problem.
Incidentally, many manual cameras wind the film on the take-up spool like the AE-1 does, including Nikon F, F2 and F3. So I suspect this is a common problem. All the newer "autoload" models wind over, in the manner of the F1.
