Here's the first light image from the 4" X 5", three hole POC camera. It worked reasonably well once I got my head around three inverse images projecting onto a single, curved film plane, lol… So I’m moving on to the four hole 120 version now. Stay tuned ;).

Me too! I have worked out the ray trace maths for the 120 based, 4 hole version with a 225mm diameter core wrap and a 4 X 5 based, 3 hole version with a 44 mm core wrap as a proof of concept. I have that one designed (see image attached of the enclosure design) and will 3D print it later today...

I'm on the look out for something without any numbering if possible. I have ordered a test roll of "x-ray" film from photography project as a test... Well, actually I am still working through the raytracing math to see how gonzo I can actually go. I'm hoping to have a 250mm diameter core to wrap...

Thanks. I'm also thinking about using Ortho film on this build because it's looking like it will be a total pain trying to load pan film in complete darkness.

Thanks, I will. It's going to be one of those crazy builds with the 120 film wrapping around a center core being exposed with multiple pinholes.

First TY .... OK... so if I black flock or matte black paint the film backing support structure in the camera that carries the film would that mitigate the halation issue ? Or maybe I should just attach the paper backing to the film support structure and change it every so often... Hmmm, kinda...

Simple question… I hope. Can I shoot 120 film without the paper backing? I have a pinhole project in mind and I would like to use 120 film but without the backing which would make it easier to load / unload the camera… I know that sounds crazy but in this particular case it would. The film would...
