BTW, something you all pinholers may find useful:
Optimal Pinhole Diameter:
1. Pinhole in SM body cap (f.l. 28.8mm): 0.20-0.25mm
2. Normal Pinhole (take RS Elmar, crush glass
and take out, put pinhole sheet inside): 0.25-0.33mm
3. Tele Pinhole (unscrew 90mm SM Elmar lens head,
put pinhole inside, shoot): 0.30-0.45mm
Examples (2 photos made yesterday with too big (0.50mm)
pinhole in Leica ScrewMount body cap (actually a shortest
extension ring)):

Pinhole details: made from steel sheet, with sewing machine
needle and too big hammer; after one, VERY DELICATE punch,
needle went through sheet making *way too big* pinhole.
What I'd to do? Took it and tried..
