I found these nigella blossoms in a natural triangle. For post-processing, I added a touch of noise to soften the lines just a little. With all those fine, hard lines, sharpening did not improve the image the way it normally does. I also used the Levels tool in Aperture to increase the tonal range. Camera was a Nikon D90; the lens, Micro-Nikkor 60mm AF.
Apparently in some part of the world Nigella is a cook of some repute. Sorry if you were expecting that, but there’s a link below if you need.
