On Sunday, April 28th, take a break from your digital devices to spread the unusual beauty of a historical photographic process as the world celebrates Pinhole Photography Day. Now in its thirteenth year, the event celebrates and promotes the lenless method that dates from the 10th century. Join thousands of people (pinheads?) from around the globe in the simple act of making a pinhole photograph by adapting an existing camera or making your own out of a light-tight container, such as a box or a can, with a tiny hole in one side. Leave your perfectionist tendencies at home with your digital camera, because, according to Pinhole Photography Day organizers, "This is the photography of patience, of meditation, no more anguish for a 'badly turned out' photo."
