This is a Myotis bat I photographed in the Sonoran Desert of Arizona. I used two flash units set up with an electronic beam placed in front of the flower. When a bat broke the beam, the flash units were triggered. This was done at night without any ambient light; in other words, it was so dark I couldn't see anything until the flash units fired. It's utterly remarkable how bats an navigate in total darkness. I could feel the air moving around my head as bats were flying in the dark, and I'm really glad their echolocation was working! I took this shot with a 16-35mm wide angle zoom, and the settings were 1/180, f/22, and 800 ISO. The shutter speed had nothing to do with the exposure. The exposure was manipulated by the lens aperture, the ISO, and the distance of the flash units to the flower.
