For me, one of the nice things about traveling with my iPhone is that I have a camera always with me—and a post-production digital darkroom always with me too. So I am never bored when by myself waiting for a train or sitting in a restaurant. In the restaurant, I can photograph the place setting, and shadows that are created, then process the photo. With luck, if there is connectivity, I can post the finished image online before my entree arrives!
With this image, I was primarily interested in the differing way the shadow from my glass fell on the table cloth as opposed to the way the shadow falls on the wood of the table itself. The bright, curved lines within the shadow are created by bright reflections off the water in the wine glass, but they aren’t quite aligned at the borders of the cloth and wood, due to the differing refractive qualities of the two surfaces.
