Firmware cracks for Canon P&S to enable RAW shooting and other things.

(If you didn’t understand this, then best you back away slowly from the link.)

Could this be the future, Open source meets photography? one part of me says oh I hope not, but the other side of me says, if they won’t make a camera to my specs, then let’s hack it!


CHDK is a firmware enhancement that operates on a number of Canon Cameras. CHDK gets loaded into your camera’s memory upon bootup (either manually or automatically). It provides additional functionality beyond that currently provided by the native camera firmware.

CHDK is not a permanent firmware upgrade: you decide how it is loaded (manually or automatically) and you can always easily remove it.

Please see the FAQ and the Firmware Usage page, as well as other pages on this wiki, for more specifics on supported cameras, details of features, scripting, downloading, etc.
