Post Oak reflection is an image of the facades of townhouses at 3050 Post Oak in houston, reflected in the pond across the street. The ripples in the water were driven by a light breeze, aided by the resident ducks. I had to wait a while for the ducks to leave the scene and I was aided in that by a child and his guardian who came to feed them a short distance to my left and out of the frame. Like Jay Maisel says, pick your background and wait for something to happen in front of it.
