Turn Your Point-and-Shoot into a Super-Camera

If you're using a consumer grade point-and-shoot Canon digital camera, you've got hardware in hand that can support advanced features way beyond what shipped in the box. With the help of a free, open source project called CHDK, you can get features like RAW shooting mode, live RGB histograms, motion-detection, time-lapse, and even games on your existing camera. Let's transform your point-and-shoot into a super camera just by adding a little special sauce to its firmware. http://lifehacker.com/387380/turn-your-point+and+shoot-into-a-super+camera
