Looks very interesting. Now show us a picture of the output of the camera please.

Focal length 100mm, micro drilled pinhole in .002” brass shim.
Sorry, I do not have any images taken with this camera, but did have one from the other camera I just posted.
GaryK, You put the film holder in the back, pull the light slide, uncover the pinhole for several second to minutes depending on the light.

Dkol – I knew that, what I should have said was do you have something for the image to be seen on to frame your subject or just point it in the general direction.

DaveR: F256. Haven’t had any flare problems with the other cameras I have made, I blacken the inside brass with a sharpie.
GaryK: Sorry, about that. It is mostly point and hope on the composition. I do use a level to “square and plumb” the camera up before I shoot. I am a believer in serendipity when shooting pinholes.

Very nice! I’m an xray tech and sometimes we’ll make these out of supply boxes to ‘play’ with.Mind if I duplicate your design? ;-)

Great project Dkol. Are you doing your own processing? What type film, paper are you using? When I hear pinhole, I usually think of a cardboard box with a pin hole punched in the front. Not any more. Nice looking camera. I’d say that with f/256, you don’t have to worry too much about focus.

Thanks for all the comments.
I have about 35 years of photography experience and it was the desire to make a pinhole camera that started me off on my woodworking adventure. I have made six so far and with the exception of the first prototype they have all been sold or given away to friends, I kept the crappy one for myself.
Scot T: duplicate awayjuniorjock: I have a fully equipped darkroom and am able to process and print film up to 8X10. I do not have any one film I use, whatever seems best for the situation. In the last couple of years I have been working with Alt processes such as VanDyke, Cyanotype and Gum.
A great resource for all things pinhole and alt process is F295.org?
I am willing to answer questions or help as much as possible, I might even have a few drilled holes I could part with.

Would you have any interest in selling this camera? Thanks for your consideration.

Sorry the camera was a commission and is long gone. The only camera I have available is the walnut and maple extreme wide angle. I would be more than happy to build one for you if you don’t mind waiting.

This is beautiful. What advice would you have for a student who is interested in building something similar? I’ve looked at a bunch of sites on the web talking about how to build one, but nothing in the way of schematics or visual tutorials. As someone without much woodworking experience, where do I begin? This is by far the most drool-worthy pinhole 4×5 I’ve seen on the web!

Dan,Where did you find the spring hardware?Cheers,Ryan

I made the spring assembly myself. Found the spring steel at the local metal mart, the pin/pivot assembly was made by modifying some nickel plated hinges.
A few years back I did a tutorial for making the springs on another forum, zip me a PM and I will send you the link.
