This is pretty cool. Peter Funch sets his camera up, takes photos over a span of time, say 2 weeks, then composites all of the images together with interesting results. Check out more here. My dad, who adores airplanes, would really love the top photo. If an airplane meanders its way across the sky, he will stop what he's doing and follow the progress of the airplane until he can't see it anymore. It's one of the quirky things I really, really like about him. Maybe one day I will do a photo series of him watching planes.
