That is a great photograph! Mine however...
I put a bit of pop can behind the lens of my Helioflex ... with a pinhole. Talk about pinhole photography, right? ROFLMAO!
I forgot that it would be better to put the pinhole in FRONT of the lens. (Why? Because I'm out of paper and the shutter won't stay fixed and I'm tired of opening the camera.)
P.S. That's a skirt hem with lace, if you're curious. Fujifilm Acros Neopan 100, inside, under a 200-something halogen light and the overhead fluorescent. I didn't take very good notes but that was around an 8-10 second exposure using the lens cap as the shutter.
