MAKE Flickr photo pool member Jonny McPicsnstuff posted up his first pinhole camera project along with some really nice photos – “Made out of a sponge bob squarepants tin I had laying around (I think a watch? came in it…no idea). The design was inspired by the Matchbox Pinhole Camera. Very Fun! I calculated with Photoshop that the pinhole is .19mm and has a focal length of 29mm. It’s about F145.” – Link.
