The second thing I learned today: Digital cameras can see infrared light, invisible to the naked eye. Or at least mine can. A simple test: Put your camera in b+w mode. Point a TV remote at it, and press one of the buttons that keeps signalling as it's held down, like channel+ or volume- . Hold the camera so that you can see both the remote and the camera's LCD screen. You ought to see the infrared LEDs flickering on the camera's screen, and nothing at all happening in real life. It's more than a little spooky.
