I made my own pinhole camera for the RB67 back. Designed a rail for the back and CNC milled the box. Pinhole itself is on aluminium tape and handdrilled with 0.3mm drill. Dunno what the diameter is actually.

Shot the first film and I have to say I'm not going to start building "real" cameras any time soon The back / rail has some nasty light leaks but maybe.. those add some characteristic? The focus is so and so. Also I undexposed the film too. All the good things!

That's impressive! I wish I had some woodworking skills.

I don't have, that is why I use CNC mill. If I ever drill or cut anything with my hands only, it's allways off and looks like crap..

Looks great!

I was thinking about building a pinhole camera that uses a roll film back, especially when I saw this:

The essence of pinhole photography: experiment and have fun!

Neat! Think it would work with a 6X8 or 6X9?

Nice. A couple of thoughts - you might find that some thin black felt on the surfaces where the film holder meets the back (ie back and sides), would cut down on light leaks. I also like flat-black spray paint on surfaces that might see light from inside or outside the camera. And, focus on a pinhole camera is just dependent on the size and quality of your pinhole; the back doesn't affect it.

Thanks for comments guys! Yeah I was a bit sloppy on this build. Most of the light leak came from the darkslide side of the 3D printed part. The 3D printed plastic probably leaks also thru the material so I need to paint that one black.

I've already printed new design of film back holder (see my previous post) and I got a laser cut pinhole from germany so I will build another one soon.
