    4 x 5 movie film

    i have a contact print of two 4 x 5 b&w movie film frames with the code
    AC 43 52342 in one of 3 perforations.

    Can anyone identify the film and what camera(s) might have used it?
    Image date is 1961.

    You should send a PM to the user "Photo Engineer", he used to work on the photographic part of rocket launches.
    Using film since before it was hip.

    There's aerial rollfilm that comes in that size, and "AC" might stand for "aerial camera," I suppose. Is there something like a Hulcher high speed camera that shoots it? Those don't look like perforations, because there is an image inside the "holes." I'm guessing that's just the pattern of the film gate.

    As measured on the 8 x 10 contact sheet the frame dimensions are 4 x 5
    with the "perforation pattern" inside the 5 inch side.

    hi art

    is the film 1 single sheet with 2 images,
    or single sheets and images?

    my very uneducated guess is that it was aerial camera
    that shot a long roll of 6" aerial film which was later trimmed
    to the rebate marks ...

    what a great piece of history you have!

    As it is hard to tell from that scene what the frequency of those images is, it does not neccessarily mean it is a motion picture in the more common sense.

    The camera camera could be a still camera, a simplified version of a 5" film mapping camera or just a simple aerial camera, but whith enhanced exposure frequency.

    What is puzzling though is the images lack time information. Well, one could do some synchronisation and afterwards look up the time via a frame number list. But a time signal directly accessible from the image would be more practical.

    But I'm sure PE could give us all details.


    Edit:
    I just realized that there is not even frame counter, just the same code for all images.

    Hi John,

    I have only the contact sheet. No captions or markings on back side.
    I can't see the Titan s/n so I am not yet sure which launch it was. I did
    crop out the exposed black of the print on my scan.

    Thanks to all who have responded to date. I believe I do know Photo
    Engineer from several years ago at Graflex.Org. He was and is a great source.
    I have seen several reels of 5-in film before...transparency stock.

    Hunting around a bit, Hulcher 70mm cameras that can shoot 6x6 or 6x7 were used photographing for rocket launches. They could be enlargements from 70mm using something like a Saunders Proofing Easel, which makes it easy to print four 4x5's on an 8x10" sheet. I use one to print batches of post cards.
