Sorry everyone, but this sounds NUTTY! How would you 'expose' for a long
enough period of time related to a pinhole exposure?! I think you'll
just get an out of focus scan of the inside of your 'pinhole box'. It's
the sanner that is projecting light out, not absorbing it like film.

We do have good imaginations, though don't we, on this list;)
