Sunday, April 29, 2012, is cause for celebration, as it is Worldwide Pinhole Photography Day. Pinhole photography can be either very simple or complicated. In its simplest form, it involves using a light-tight box (like an oatmeal container or coffee can, below), inserting either film or photographic paper, and exposing the film to light via a hole with a tiny aperture (ie: the size of the head a of straight pin) that you've made in your container.
My two homemade pinhole cameras (above) are pretty simple, but some are really lovely and elaborate. I also fashioned a pinhole apparatus from the body cap for my Canon Rebel T2i, which I used to take the below photos. But I quickly discovered that pinhole photography behave differently on a digital sensor. Because of the small size of the sensor compared to a 5"x7" piece of photographic paper, diffraction is much more sever on the sensor, having a very negative effect on the sharpness of the photo.
On Sunday, I'll post some photos I made with my digital pinhole setup.
