this was inspired by lisa's amazing double exposure photos. well more ripped off as she has got exactly the same shot but its ok as you can see that i have managed to line up the middle dome exactly! also this was shot on an lomo LC-Wide and hers was on a lomo LC-A+
she wrote a chapter of double exposures in a little book called Photo Op / 52 Photographic Projects you should check it out.
