In a world where photoshopping is acceptable verb usage, transparent photography loses a little bit of its magic. Though I suppose it’s hard to look at some and not think it’s marginally cool.
It’s simple to do. First pick a decent subject – a refrigerator, car hood, computer case – then place your camera in a stationary position. A tripod works best. Then take two photos; one of your subject closed, and one with it open. Some simple layering in PhotoShop will complete the composite. Peek-a-boo!
