Create A High Contrast Graphic
I couldn't find a B&W photograph that I liked, but I took this colour photo, desaturated it and set the contrast to high several times. The second photo is the result. It's a bit too busy for a logo, but if I can get a shot of a single Snowbird, I think it would make an excellent rollover image.
