andrew --
i didn't make the hole myself for this camera .... it is a manufactured hole, laser cut i imagine, into what looks like brass shim stock -- i took it off a 3" tube-type pinhole camera that was given to me by a friend, photographer kurt norlin, and i put it on the cigar box, which is about 3 1/4" deep .....
joelr --
the only pic i have is one i took with a digital camera during the long exposure of the covered bridge -- since it's digital i can't post it here, so i'll email it to you ......
