If you’re using a consumer grade point-and-shoot Canon digital camera you’ve got hardware in hand that can support advanced features like RAW images. Canon Hacker’s Development Kit (CHDK) is a firmware enhancement that supports an impressive array of Canon digital cameras.
It’s also totally non-destructive — meaning it makes no permanent changes to your camera — and certainly makes some of the cheep point-n-shoot Canons into much more capable cameras.
I personally love my Panasonic, but a lot of Canons run on normal AA batteries which is a serious advantage when you’re traveling.
