Gaillardia x grandiflora, photo by Harold Davis. View this image larger.

This flower is a Gaillardia x grandiflora ‘Oranges and Lemons’. Gaillardias are native to North America, and are sometimes called Blanket Flowers because of their coloration.

I’m using an eight foot long raised bed in my protected side yard to grow flowers for photography, and this Gaillardia is the first subject. As models go, I think my flowers will prove to be very pretty and cooperative. Another benefit: they don’t seek modeling fees.

I photographed this flower on a black velvet background using diffuse natural sunlight. A previous experiment had convinced me that a single point of focus wouldn’t create an image that was sharp all over the flower. So I made twelve varying exposures at three focus points, and hand layered them together for an HDR and HFR image.

[Nikon D300, 200mm f/4 macro lens (300mm in 35mm terms), 12 captures at shutter speeds from 1/2 of a second to 8 seconds, all at f/32 and ISO 100, tripod mounted.]
