I have been interested for sometime in multi-exposure and superimposing subjects across time. This image is not a multi-exposure in camera instead it combined two photos taken only a short interval apart. It was just on dusk and there two ducks where lazily swimming by. I already had though of the idea of using flash and non-flash for the multiple images so I grabbed my camera and two a couple of photos, trying to keep the ducks in the center of the frame.
Back home I put the two images together but it was quiet boring because light water in the normal exposure cancelled the dark water in the flash photo (it a boring blue/grey)and the ducks where cut in half because they did overlap. So I had the idea of using a luminosity mask in OnOne 10. First I used a dark brocade textures layer and replaced the lighter values in the photo (the water) and kept the darks (the ducks and shadows). Next I overlayed the flash image and using an inverted luminosity mask let the blend bring the modified original photo and texture into the dark background. A slight crop, leaving the illuminated duck swimming on a surreal surface, with their available light selves becoming living shadows,
