APUG peeps, I've noticed that this forum hasn't been used in a WHILE so I thought I'd mention a contest which I ran across while doing pinhole research..this guy, Chris Keeney, looks pretty cool and his website is really well done. (not sure if he is a member on here or not) He wrote the book: http://www.amazon.com/Pinhole-Cameras-A-DIY-Guide/dp/156898989X and although I myself have not purchased it, it has tempted me and it has really good reviews. He currently has a pinhole contest on his website: http://chriskeeney.com/pinhole-cameras-a-do-it-yourself-guide-2013-photo-contest-gallery Only qualification, he says is "The contest is open to anyone who has read my book to help them make their own pinhole camera." You can read more info on the site. Happy Shooting.
