    Hi Ive been a lurker, but I joined to ask this question since Ive been delving into alternative processes lately.

    Would this work:

    Using a 35mm camera, place a small black piece of card stock or doubled over fully exposed litho film with slit, behind shutter. block out viewfinder, insert roll of film. with lens cap on, advance to 2nd to last frame. set lens to a small aperture, cock and trigger shutter in bulb and hold, trigger rewind button, take off lens cap, and rewind film manually back into cassette, all while on a sturdy tripod.

    Would this be a quick, viable, and easily reversible conversion? or would i just get a long smear?

    In Pinhole Photography 4th Ed. by Renner, the author has a short excerpt on a photograph by Jonathan Trundle, where he mentions the use of a heavily modified hasselblad on tripod, using hand winding to get the slit scan effect, but did not provide further information. (P.211 Figure 7.17)

    Would it work?:confused:

    Welcome Newt,

    Interesting idea. I don't know why it wouldn't work.

    In thinking about this for a few seconds it could be real fun. A bit more complicated that walking and chewing gum though. :wink:

    You might also consider a camera that is already dead too.

    This Lomo would lack the "i did it myself satisfaction" and is not exactly cheap but it's not too expensive.

    Unless you are moving the camera at the same time as winding the film, you will get a continuous image of a very small section of the frame. A similar system is used for photo finish pictures at horse races. The film moves at the same speed as the horses so they appear in the order they cross the line. The background is of the finishing post on the full length of the film.

    There isa picture from one here: http://upload.wikimedia.org/wikipedia/en/8/81/Pic_race_1_12192005.jpg As you can see, the background is a continuous reresentation of a very small vertical section.


    Steve.

    thank you! good suggestions

    The lomo camera is a good idea but its kinda pricey at $135 for just 1 intended shooting style, and I dont think the optics would be as good as one of my cameras.

    As for the stationary camera/ photo finish effect, I was hoping to shoot moving objects, maybe something like a carousel, or an escalator with people, and trying to capture that elongated motion.

    attached image is sort of what i want.

    You are seriously underestimating cheap cameras.

    It is a regular occurrence for my $29 Holga to kick my Nikon's butt, of course it's just as regular for the Holga to give me trash, that's ok.

    i know that the sfx team for 2001:Space Odessy used the slit-screen for the Jupiter sequence. I believe the slit screen was placed in front of the lens. have you played around with these? I may be in the wrong ballpark w/ the effect your going for-but I've done similar stuff with the aid of an optical printer for 16mm.

    I made a servo controlled camera using an ME super and a cardboard slit over the film gate. It works fine, but I need to improve the mechanics of it, and the project is in a basket because I'm moving.

    Here's a super massive example pic here:
