Pinholaroid1
Adrian shows you how to make a pinhole camera from an old Polaroid – “I picked up a Polaroid camera for $1 at a garage sale thinking I could add a pinhole and have a pinholaroid. I didn’t find any good online tutorials, and feeling confident after building my digital pinhole camera, I decided to figure it out as I went.” – [via] Link.
