Re: pinhole is not about "sharpness"?

Eric,

To make your body cap pinhole closer to the film plane would make it get
in the way of the mirror. You might need to find a range finder camera
so that you can recess the hole. My image for WPPD 2001 (#95) was made
with a Leica that I had made a 15mm recess adapter. I made this out of
the stand pipe from a patterson developing tank, cut 15mm from the
bottom flange. The bottom flange is wire enough to span the lens mount
opening. I attached my pinhole to the open end of the tube and attached
the flange to a screw mount to M adapter so that it was an easy mounting
fit.

Last year I was able to get my image up on pinhole day, this year I've
been slow about it. I hopefully will get it posted before the #500
