Light Blaster Session: No. 9 by budrowilson, on Flickr

The interesting thing about this shot is that it was captured in-camera. Yes, I did some post on it (increased clarity to make the projected scene more recognizable on the background), but for the most part, it's just as captured by the camera. While I think that some of the double exposures turned out better, this one ended up being one of my favorites. The form of the woman is recognizable, but the features that really catch your eye are the details in the projected slide. And the fact that there is continuity with the elements in the background (though the details are less discernable) make it all the more interesting, imo.
