I love digital photography - the endless reuse of materials, not needing to make prints that may or may not be good, the frolicksome sense of freedom - but I can see the appeal of World Pinhole Photography Day, (as mentioned on flickr blog). It's a good idea to step back from increasingly sophisticated and controlling technology to hand-made, home-made, a little gadget that expresses natural beauty and basic science, resulting in a creative work that's all your own.
Pinholeday.org has some good instructions on how to build a fairly sturdy pinhole camera, and also how to figure out exposure times, with notes that really, a cardboard box with a hole in it and some film inside works too if that's all you feel like doing. Or you can expose directly onto photographic paper, to create a one-of-a-kind sun print.
Group events are taking place everywhere from Bristol to Bangladesh. Participants are encouraged to scan their results and upload them to the permanent Pinhole gallery. For such an imprecise art form, the results can be quite beautiful, as evinced by Daryl Furr's laundromat photo to the right.
