Falling in Love on White, photo by Harold Davis. View this image larger.

This is the Papaver rhoeas ‘Falling in Love’ that I photographed on a black background. The version here gives me the advantage of a “twofer”: I created the white-background version of the photo in Photoshop by inverting the Luminosity channel (in LAB color mode), then copying the orginal flower back on top of itself, and masking out the black. A few tweaks followed, but that is the general idea, and it is pretty simple to do. Which version do you like better?

[Nikon D300, 200mm f/4 macro lens (300mm in 35mm terms), three exposures with at 1/2 of a second, one second, and 2 1/2 seconds, all exposures at f/36, ISO 100, tripod mounted.]
