    Wild idea - auto sheet film holder

    Since we are on the subject of wild ideas.. how bout a new sheet film holder.

    1. holds 20 sheets of film (maybe a fat model comes out that holds 50)
    2. a roller on the side moves 1 sheet from the storage slot to the live slot.
    3. exposure is made
    4. roller moves the single sheet to the back of the storage slot.
    5. a divider keeps the exposed film separate from the unexposed.

    Could be motorized or manual drive.
    With the experience of printer paper handling tech, I would not think this would be too hard.

    More film used = more film bought.

    Well, I shot 70 sheets of 5x7 on Friday, but I am the exception to the rule. Many LF photographers shoot just a few sheets a day, once a week or so.

    There was a manual version of this idea, it was called a film pack, and Kodak and Ansco and probably Ilford and DuPont all made film packs. The film was thinner, so it could fold around the bend when the tab was pulled after exposure, pulling the film to the back of the pack. Film pack products were discontinued due to slow sales.

    You could shoot as much or as little as you wished. Just empty out the film from the holder with the lever set to "unload" when you are done.

    I have never used one, but it would seem to me that the film packs would not keep the film as flat as a double-d holder. (hmm that just didnt come out right=])
    Anyone here ever use a film pack? were they just for press style shooting?

    Graflex has done this a long time ago.

    There was one that held 50 sheets made in L.A. if I remember correctly in the 1970s or 80s.

    Kinematics held ten, and Kindermann also made a more recent ten sheet holder up into the eighties.

    And back in time, there were even bigger ones. Besides the Graflex bag-mags (at least in flavours of 12 and 24), there were German made wooden 12 plate/20 sheet mags at least up into the thirties, for most sizes and attachment types - I have one for my Mentors and have seen others for Normalfalz backs.

    I saw pictures of one that reportedly held fifty 5x4 sheets. A motor drive. Looked like a cool little beastie. Didn't someone try to sell one like that on LFPI a year or so back?

    Motorized aerial back. 5" or thereabouts roll film.

    What about just updating the grafmatic in modern hi-tech polycarbonate or other suitable material? Light weight materials with low friction properties might allow a moterized version as well as the manual model.

    There are only three types of mounting flanges; too big, too small and wrong thread!

    I saw one on eBay around then, and there was a thread on it, and one person who had used one, I think.
