RE: closeup pinhole camera

Have you ever seen a finger print camera? The ones I have seen have a
4x5 on a fixed focus lens and a hood in front of the lens that housed light
bulbs. You just fitted this right over the fingerprint, flush with the surface
and snapped the picture. If you just wanted to shoot the objects flat on the
ground you could make something simular with a flash within that hood to
provide your lighting.
