I just got back from Botswana. On the way up from Joberg, we stopped at a lodge called Elephant Sands. It has a water hole and I was told that ele's drank there each night. It was a moonless night with a very full milky way in the sky. Everyone around the boma laughed as I set up my camera and shutter release and pointed it at the dark watering hole... but I heard the ele's and could see the sky, so I started shooting 20 to 30 second exposures. With that much time, I assumed the light from the lodge and the fire would allow the trees and any ele on the far bank to be seen. Good guesswork. This may not be my sharpest image from the safari, but it may turn out to be one of my most prized:
