This is a close-up fisheye of my Leucospermum Scarlet Ribbons. I photographed the flower with the Lensbaby Composer and the new Fisheye Optic.
The image you see is a hand-HDR composite of five exposures, all at ISO 100 on tripod. Each exposure used the f/22 aperture ring. Exposure time ranged from 1/4 of a second to 1/30 of second.
