Pinhole Camera
23 April, 2011
Back in the film era, pinhole cameras were at times quite popular. The didn't have any glass in the lens, just a pin prick to let light in and expose the film. Because the aperture was so small, there wasn't any sense of depth-of-field with the photos because everything was in focus provided that the hole was the appropriate distance from the film.
In theory, the concept should be quite transferable to digital photography. After all, the sensor in a DSLR functions just like the film in a camera so by making a tiny hole in the body cap (the protective cap you put on the camera when there is no lens attached), the camera should be able to resolve an image. I tried it out and got it to sort of work. The photos are out of focus because the distance from the sensor to the hole isn't quite right, but with some refining, I should be able to create a way to take some really cool photos. Here's a few up on a Flickr gallery (click here) as sort of a "proof of concept." |
