Here are some handy tips on turning it into a cheap, cool lens for your DSLR. As a bonus, it also works as a macro lens for your smartphone! It’s all totally reusable, so in theory, you could shoot a VR movie, stick the lens back in the cardboard viewer and then watch your masterpiece with the same lens. If you want it to focus better, just stick a piece of construction paper between the lens and the camera.
Try experimenting with different size holes: The smaller it is, the better the focus and longer the depth of field will be, but you’ll also need more light (just increase your ISO and use a longer shutter speed). On the other hand, if you’re going full-on pinhole, you probably won’t need a lens at all. Always be careful not to get too much schmutz in your camera – I’m told that’s no good for the sensor. Big thanks to Google, Canon, Apple and the Sundance New Frontiers section for all their hi-tech awesomeness!
