NOT PHOTOSHOPPED. It actually came out like this.

The left-hand side is a mirror, and the right-hand side is clear glass, with Alisha standing on the other side.

To those of you saying it's shopped, see this photo for context:

Taken here: Peggy Guggenheim Collection, Venice.

The only alteration I made to this photo was iPhoto autocorrect and a little fiddling with contrast.
