This is a technique I have been working on perfecting for several years. It involves overlaying two images of different subjects for artistic and abstract qualities. I always do these "overlays" in camera, my Nikon's allow multiple exposure and image overlay in camera. This shot is a shallow focused image of wet lupines in the early morning light and second image of a 10 exposure multiple pan. As I mentioned before, the images were combined in my Nikon D700. Minimal processing in Lightroom V3.
