In preparation for World Pinhole Photography Day (April 19 this year), I got out my ZeroImage. I set it to 6x9, but the images come out more like 6x10. I probably gave the HP5 a little too much exposure; TriX may have been more accommodating.
Looks good! (Glad you posted this, as it hit me that WPPD is fast approaching and I had failed to note it on my calendar -- however it's the 29th -- last Sunday in April, so I have a bit more time to recover from my momentary panic. )
