I was lazy, so I made a new lensboard for my view camera with a piece of
thick cardboard. I cut a hole in that with an Xacto knife and taped a
piece of aluminum foil over the hole. I punched a hole in the aluminum
with a sewing needle. I racked the camera to about 8 or 9 inches, stuck
a Polaroid holder in it with a sheet of #57 in it and pulled out the
paper. After 30 seconds or a minute or so, I put the paper back in and
processed it. Came out pretty well. Not as sharp as with a 210 mm lens,
though. Since I am not especially interested in pinhole photography, I
did not do any more. And now I do not know where to get Polaroid film in
4x5 size anyway.
