I photographed this white Amaryllis unfurling using dappled and diffused sunlight for illumination, and a black velvet cloth for the background.

The image is comprised of three exposures, each using the Lensbaby 85mm f/1.6 and an extension tube, with my camera mounted on a tripod. I varied the aperture (and adjusted the shutter speed to compensate) to take advantage of the different effects this lens has depending upon how wide open or shut down it is. The exposure at f/1.6 yielded the bright sunlit areas on the upper right, the exposure at f/4 covers most of the mid-tones, and the exposure at f/16 sharpened the inner unfurling.
