3D printed 6x18 camera

How well has the pin hole worked. Any example images?

I wait with eagerness for an update on this project.

I have some result.
The first roll got started a bit on the side so it wasn't spooled up correctly, not the cameras fault but mine.
So the first roll did get some light strikes on it's side but the second rolled worked better.

I'm not an experienced pinholer so the images are not the best, I didn't compensate for any reciprocity so some are a bit under exposed.
This was more a test to see if the camera is light tight and if the film wind was working correctly and all seems fine.

Just need to make some adjustments in the film compartments so I can "angle in" the film, now I need to remove the film knob in order to get the film in and then attach it again.

Very very good results!

Looks great so far! The plastic seems to be light tight as well, or are you experiencing any fogging? .

I bought a couple of lenses now, a 65mm and a 90mm so now I have a reason to finish this project.
I made some changes and decided to go with premade metall cold shoes instead of printed ones.

These are the cold shoes I will be using.

Cold shoes can also be milled out of metal.

Nice to se you are making progress ))) Could you please share with us what lenses you've got? Also, would any medium format lens work with this camera, providing I can fit it? I have two Carl Zeiss Jena lenses, the 50mm f4 and 80mm f2.8 made for Pentacon Six camera. Would they work if I can print/buy the right adapter? Thanks

They probably don't have the image circle required to cover a 6x18. You'd be lucky for them to cover 6x9. This would require large format lenses.

Are they in shutter? If not, how will you get timed exposures?

OeT · Oct 2, 2017

I will use a Schneider Super-Angulon 90mm f/8 and a Nikkor SW 65mm f/4 lens and as other have mentioned a large format lens is to prefer.
Also made a cone for the 65mm lens

OeT · Oct 8, 2017

65mm lens cone printed

Also working on a spring loaded film advance and holder

OeT · Oct 13, 2017

Two lenses have arrived

And I added a attachment point for a shutter release cable

OeT · Oct 14, 2017

Worked some more on the winding mechanism

I've been following this thread. Really interesting what you can do with a 3-D printer. I'm looking forward to seeing your first images with a real lens. I do think that the pinhole images showed the utility of your camera, but I really want to see how it performs with a good lens.

OeT · Oct 22, 2017

I will probably take out for a test next weekend
In lack of a real viewfinder I made a holder for a door eye to help with framing.

jon.oman · Oct 22, 2017

Now, that is cool! I would love to have one of those.

Eric Rose · Oct 22, 2017

This is the kind of stuff I love to read about. Thanks for all the detail and progress pics.

I'm not sure I ever saw a camera with such snapper to hold the back. Where did you obtain the tiny snappers? From your parts box or from some shop?

Thanks all
The clasps are from a store here in Sweden that sells machine parts and such.
The smallest ones they had

Just curious (and I know little about optical formulas and such) - I know many people like using an old Agfa Clack camera for Pinhole, as it has a curved film plane. How would that work with a pinhole for a format this wide? Would it help with film flatness (the tension of the film against the pressure of a curve under it?).

AgX · Oct 23, 2017

As the DOF of a pinhole camera is infinite there is no reason to bend the film plane, in contrast to some lens cameras.
However for perspective reasons and light falloff one might consider bending the filmplane with a pinhole camera.

Any update on the lens version? Any test images?

Thanks!

I took it out for a test today.
Hopefully I can get some scanes up by tomorrow.

Some pics of the finnished camera.

jon.oman · Dec 3, 2017

Very nice!

Wow, that came out great! I can't wait to see how the shots came out.
