I think you are likely on the right track with those ideas. The first thing that came to me was the notches on sheet film, but those would have produced black bumps intruding on the image area. As I recall from my early darkroom days, those notches were mainly for properly positioning the emulsion side of the sheet film in the holders. If the purpose was to encode information for something like slide mounting, it seems like it would have to involve some optical sensing and automated processing. I guess that was a possibility in the late 1930s, though I've never seen any good descriptions of Kodak's processing technology from that era. I guess I could try to contact the Kodak museum in Rochester to see what they have on the subject. |
