One more thing ... Time-Lapse

See this ... artsy time-lapse shots created for the Conan O'Brien show..


Then some great how-to from the guy who made them..


An option for controlling your camera for time-lapse is the Trigger-Trap app and cable.  It is cheaper than the camera controllers from Canon or Nikon, with a lot more features for triggering your camera with sound, motion detection, WiFi etc.
