This is the reflective plate for an on/off switch in our dining room, reflecting the lights from our Christmas tree. To make the image, I made three versions, with each shot using my 200mm macro lens on a tripod, at 1.3 seconds at f/5.6 and ISO 200. Each version was focused differently, with the out-of-focus versions yielding the interesting reflected lights.

I combined the differently focused versions in Photoshop, starting with a stacked composite of all three photos.
