A Pinhole, Lens, and a Shoe-Box make a Photograph....
Admin note: one of the great things about DIY photography is that everything is possible. (Robert Hirsh refers to this as the Possibility Scale). Here's a wonderful little experiment that yielded an equally wonderful image! Many thanks to F295 participant Monsieur Be for posting!
Here is a first test of a large format camera made with a simple shoebox and a lens + pinhole. I dismounted an old focal doubler and found a meniscus lens of 120mm of focal length. Then I placed in front a pinhole of 1.5mm made with a black cardboard and using a biopsie punch. The camera looks like a pinhole but with a lens. The aperture is about f:90, a bit more sharp than a pinhole
I made a first test with some pre exposed RC paper.
