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

Briefly noted: I grew this delicious Sunflower for the purposes of photography. Putting it on a black velvet background, I made five exposures at shutter times ranging from 1/2 a second to four seconds. With the darkest exposure on the bottom of the layer stack to make sure the background was black, I layered each of the five lighter versions of the Sunflower on top one by one, moving from darkest (shortest exposure time) to lightest (longest exposure time).

More Sunflowers: Sunflower; Sunflower and Bottle; Sunflower (Sunflowr?); Sunflower.

[Nikon D300, Zeiss Macro 100mm f/2 ZF Makro-Planar T* Manual Focus Lens, five combined exposures from 1/2 of a second to 4 seconds at f/22 and ISO 100, tripod mounted.]
