Sunburst, photo by Harold Davis. View this image larger.

This is a tiny heliotropic (meaning photo sensitive) flower in my garden. It only opens in bright sunshine, making it hard to photograph because it’s only available in bright, often harsh light. But worth the effort, I think.

[Nikon D300, 105mm f2.8 macro lens (157.5mm in 35mm terms), 36mm extension tube, +4 close-up filter, 1.6 seconds at f/36 and ISO 100, tripod mounted.]
