Voyeur.

I was struck by some double-exposure images that I saw recently on a stall at Harbourside, Bristol; they were layered on computer and featured landscapes and architectural features.
Since then I've been struggling with making some of my own "double-exposures" with my iPhone and a few apps - not sure that I'm making much headway. I can see the possibilities............
