This hack is not for photographers with weak hearts. We’re going to be talking about destroying the body of a Single-Lens Reflex camera. But out of destruction comes something new. A broken camera paired with a flash and functional optics can be used to project light patterns for picture backgrounds.
The hardware is often referred to as a cookie projector, and a commercial unit can cost several hundred dollars. But if you or someone you know has a non-functional film SLR you’re already half way to making your own. Just snap off the back cover, yank out the mirror and shutter, and the bloody part is over. Slap on a lens with a large aperture, create your own slide with the pattern you’d like to see in your images, and affix a flash to the gaping hole on the back of the camera body. The video after the break shows the diy cookie projector hanging out on the flash stand, synchronized with your DSLR flash to add some pizzazz to the photo shoot.
