I forgot to mention, you'd have to change the light source and add a
diffuser.. small lightbox, a bounce the light off a lower wattage bulb,
maybe ad an aperture, opal glass (edmund optics) diffuser to fix behind the
frame being copied. If you wanted to do something with manual transport
manual camera, then it would be much simpler to construct (maybe hack a
moviscop for the transport), although the alignment will take some
precision.
