Raindrops are neat. Today, we took a drive to Staples and when we were there, it rained. When we got back, the car was covered in droplets, which I got some shots of, but the most interesting was the droplets on the sunroof. I took this shot from within the car and what I find neat is that if you view the full screen since, the droplets look a little like a cells when viewed through a microscope.
I took this with my Canon 7D and the 24-70mm lens, shooting at 1/40, F10 and ISO 400. Today was a pretty wet day.
