How to Create a Homemade Large Format Pinhole Camera Using a Shoebox

shoebox1

This camera is a poor man’s large format camera. It is made with a simple shoebox acting as a dark room.

The lens is a simple glass meniscus (convergent lens) that I found in an old focal doubler. The lens has a focal length of 120mm and thus a large image circle. These simple lens gives large aberrations so once need to place a small aperture in front to minimize distortions of the image.

Then I use some black cardboard paper and punch it with a biopsie tool. The hole is 1.5mm in diameter that gives an aperture of f/90. It is something between a pinhole (f/150) and a camera with a real lens (f/64)

The lens is attached in front of the punched hole with some patafix (adhesive putty tabs).

The camera is a simple box. I build it to have a distance of about 120mm between the lens and the back. The 10x15cm photo paper is attached in the back with patafix. It is loaded in red light. Photo paper has a sensitivity of about 6 ASA, so with the small aperture f/90, exposure time is quite long — about 30s for EV 11. The shutter is made with a simple piece of paper sliding in front of the hole.

The paper that has been pre-exposed 2s is developped and then scanned and inversed. The result is quite sharp compared with a standard pinhole:

    how to make this?

    where to get the lens?

  • Dee

    There is no lens, just a tiny pinhole to let the light in, and in the other side you put a film, you should cover the pinhole, if you want to take a photo you just uncover the pinhole for seconds or hours, then cover it, you have a photo, you just need to develop the film.

    Read more about it, you can make camera out any thing, just google “pinhole camera”

    The results look great! but…anyone would question the need for the lens when the aperture is already so small.

    the lens would bring more problems, than solve them. The results would be less sharp than a pinhole + with a pinhole there is no distortion.

    Umm, I hate to be picky but, although this is a cool project, it is not actually a pinhole camera. Pinhole cameras by definition only use the pinhole to expose the image. Once you add the lens it is actually a conventional camera with a fixed aperture. Nice photos, but it should work just as well without the lens. Sharp exposures would just take longer but would have the characteristic pinhole look: all items equally sharp (or unsharp) regardless of their distance from the camera.

    I hate to be picky, too, but “it is made with a simple shoebox acting as a camera.” A camera is simply a light-tight box. (Or, in the case of Holgas, an almost light-tight box.)
