I’ve gotten a lot of great responses to my Light painting with the kids video. The reaction on Youtube is overwhelming. Over 30,000 hits and counting. A lot of people on there were asking how it’s done. I put together this quick tutorial on how to setup the Canon SD900. This feature is not limited only to this model but is available on most Canon Elph series point and shoot cameras.

FOr those who have a camera that’s capable, the mode where you can manaully control the shutter (eg: it stays open for as long as you hold the button down) is called “bulb exposure” ( http://en.wikipedia.org/wiki/Bulb_(photography) ). As Mike suggests, this mode is messy if you touch the camera, so using a remote is the way to go.
