Here is the camera as projector again. The 100mm lens produces an image (through 35mm gate) that fits well into the punched paper we were planning on using for the leader project. But to save paper, registration problems and building time/money we might now shoot off an ipad screen which fits perfectly the 190mm x 138mm image. The soundtrack width is 18mm.
This one shows the peg bar above the paper so we hang the sheet from it. Once we trace around this frame we have a very accurate measurement of the shooting area covered and thus the physical size of the artwork.
TO DO:
tests projecting widescreen frames, scope frames, academy frames and 1.66 frames, infact use a test loop. Need to ascertain the relation of oxberry full gate to all other formats.
