    How to Build an Omniscope

    yeah, I can understand that, roll film will have a convenience factor
    but I'd say that more than half the fun was working it out and doing it...

    GOOD LUCK !!!

    Do you have any pics of your 'black box' or plans I can nick off you? The whole thing sounds quite easy till you get to feeding through the film. and lightleaks, etc

    Thanks also for the film counter tip - should have known that one.

    How to Build an Omniscope

    just to drop another name...
    bryak had done some great stuff with segments of 35mm film in a can.
    he's used a more "normal" orientation but the principle is there.

    yeah, this was one of those "see if you can" things, and worth it to me. i haven't seen an omniscope either, just the pics on their site. my last horribly buggy camera used shower door rollers to guide the film- that part, at least, was successful. not really necessary for the omni, though- mine turns smoothly with pvc ring guides, once the kinks in the winding path were smoothed out.

    bino makes single-picture anamorphs that are better than anything i have ever shot, but chemicals are not an option for me, so it was roll film or nothing. i decided to count rotations (4) instead of a hole, because there are only 4 frames per roll.

    by the way, i got to "play" a theremin at a scientific oddities museum in minneapolis- very fun! do you have one?

    Of topic, kind of, didn't the Beach Boys use a theremin in Good Vibrations?

    probably the best known usage, outside the 50s Sci-Fi movie sound effects. i've owned two (kept the Big Briar and gifted the other), and aside from the unit staft mentioned i found one in Fargo (see http://www.hjemkomst-center.com/ , which has/had a ''history of Fargo Radio and TV'' area ), making me wonder how many theremin's Minnesota has on display !

    Solution: Make my own OAP camera... out of cardboard.
    The least expensive solution is to use a toilet paper tube. It takes a 4x5 neg. Spray paint the inside of the tube black, wrap it in a layer or two of gaffer tape and put a pinhole on either end. Using both pinholes, it makes a 720-degree anamorphic camera. If you make four of these, it will produce the same number of exposures as an Omniscope with one roll of film.

    How to Build an Omniscope

    I have been thinking about the simple film strip in a can method, opposite curvature from S'taft & 'rew.

    Pinhole no problem, but I wonder what kind of can/tin geometry would give enough depth-of-focus with a lens...maybe put film deep inside a can at a distance reasonably approximating lens f.l, and use near-pinhole aperture?

    Like maybe the 83/84 mm Vest Pocket Autographic lens/shutter I have in a cardboard box for now, at f/64...it'll go a bit past that too. Select a tin that will allow the middle of a filmstrip to be at focus and illumination point and position film guides there.

    I was thinking a hole in the tin on the perimeter covered with frosted tape (a radial 'viewing screen) to precheck or set up distances, covered with something to seal out light...flexible magnet?

    Wow! Thanks for the advice - so many ideas. I'll try the simple tube approach 1st I think. Now here's another question: Using 120 film in a tube - and in relation to the film, how does the height of the pinhole affect the image quality? I'm guessing that thinner material should be used to make optics and that this is one of those 'try it yourself dont ask' questions. but anyhow...

    off topic - Had two Moog theremins, sold one kept the other. Simple to play; Fiendishly difficult to play well! Theremin was probably not used in good vibrations. Video shows someone playing a Tannerin, but Brian Wilson claims that a Theremin was used. Just thought I'd let you people know.
