Focus Shmocus! I'm building a pinhole camera. Check out some of the fumes I have been breathing over the past few days:
It's not done yet, but it's finally starting to take shape.
I got a Horseman 6x7 roll film back on eBay, so I didn't have to re-invent the film transport wheel. I also got an Apogeo II pinhole shutter on eBay, so I'll be able to use a cable release. The box is made with masonite, so it's very lightweight. I used pieces of half-inch aluminum angle from Home Depot to brace the pieces together on the inside and expoxied it all together. I used 3/8" aluminum "C" track from Home Depot to make the track that the film back will slide into. The focal length of the camera is 48mm, and the pinhole is 0.0102", which gives me an aperture of approximately f185.
On the cosmetic end, once the epoxy and 3M 5200 is cured, I will cover the box with some charcoal colored vinyl from the bargain bin at Joanne's Fabrics, and I will use mitered pieces of half-inch aluminum angle to cover the edges.
With an aperture of f185, using a tripod is going to be mandatory. I will probably buy a close-out L plate for a discontinued SLR model and permanently attach it to the camera.
I need some kind of handle or strap. I am debating using one of the handles in the picture above, but I'm not married to the idea. I think some kind of strap may be less obtrusive. I am open to suggestions here.
Viewfinder, you ask? I'll probably just use my Voigtlander 25mm viewfinder for now. It's not EXACT, but we are talking about a pinhole camera after all.
