Reader Photos: Thus, the pinhole camera for DSLR

Back to basics: With a little trick makes the hundreds € expensive digital camera to a simple pinhole camera, the photos as it was 150 years ago. One of our readers has tried it - they see its results. We asked our readers to retro photos - and get more than 100 letters. Among many snapshots that are created by using apps on the smartphone, but also more complex experiments.

Particularly impressed us the photos by Jens Hoesel from Leipzig. He has used his shots a Canon digital camera, but it omitted the lens. Instead, he put the cover of the camera housing on the lens thread, in which he had previously drilled a tiny hole. This turns the DSLR a pinhole camera, according to a principle that Aristotle and Euclid in the fourth century before Christ known.


Light that passes through a small opening produces a mirror image. The photographic technique was, however, added later, according to Wikipedia was the first image with a pinhole camera shot in 1850. The smaller the hole, the sharper the picture is - and the less light comes through the hole, leading to very long exposure times.

The result are images that appear uniformly distributed because of the focus-area as receptacles with lenses to focus the subject.
