I caught the slanting afternoon light on my office floor and knew I had to do something with it. But what? I started by photographing a clump of dried hydrangea in various positions but wasn’t happy with what I was producing. Then I saw a flicker of a rainbow from a prism outside and remembered a large prism I have. I like the contrast between the angles of the prism and the texture of the wood (and, of course, the rainbows!).
