To the upper right is me with a striped shirt on, trying to hold still for 12 seconds but also needing to open and close the "shutter" of the pinhole camera (a coffee can with a flap over the hole). I wanted to do some more experiments. This one contained a secondary transparency suspended inside the can but I can't see any sign of it. Unfortuanatly I needed to quit for the day and couldn't do more tests. This was done with a new can Trevor Grant and I built today. We calculated the f-stop at 120. Again, this is a paper original, scanned and flipped positive in photoshop.
