Tower Model 7

This is a 6x9 format, 120 film camera from the 1950's that I modified to be a pinhole camera.

The pinhole is 200 microns, and the focal length is 120mm. This gives an f-stop of f600!

The camera has two view finders, one for vertical shots, and one for horizontal shots. It also has a shutter that can be used in 'bulb' mode, or in 'instantaneous' mode. A cable release can be used.

Here are some images of the camera:

Here are some images from the first roll of film (the pinhole is off center!):

The exposures ranged from 51 seconds in good light to up to 10 minutes in poor light.

These were shot on Kodak Tri-X 120 roll film, and were processed for 9-3/4 minutes at 68 degrees F. in D-76 1:1.

Jon very nice images it makes too, how did you measure the hole size?
Thanks for sharing!

Sorry for the late reply, I was out of town for the last few weeks....

I used a pre-drilled lasor cut pinhole. If I remember correctly, it was from a company called EMS. It has been a while since I ordered the pinholes.....
