Last night during a pretty wild thunderstorm I set up a "water droplets" shot out in my barn to use for the background of this website. It was quite the challenge to figure out how to achieve the correct reflections/refractions. As you can see, I have limited equipment, but plenty of A-clamps. Clamped to two vintage race car rims, the Lexan has water on it and black below it. The flash was bounced off the black surface into the white surface.
