Acknowledgements CHDK has to be one of the most innovative improvements to any camera that has ever come along since the beginning of photography . Started out by some people who only wanted RA W out of their raw- crippled cameras, it has now grown into one of the most adaptable, flexible, and full-featured operating systems of any cameras ever ma[...]

! ! CHDK Introduction ! ! ! ! ® Welcome to CHDK, for users of Canon Point and Shoot Cameras Q. What is the CHDK program? A . CHDK enhances the capabilities of your camera in a non-destructive, non-permanent way . ! After loading of CHDK program your camera will have the following extra functionality: ! • ! Shutter -priority (Tv) exposure - via s[...]

These features work on all camera models supported by CHDK. The camera does not need to have "related" or "inherent" features already present - CHDK will add the required functionality . New features are accessed through CHDK-specific menus, rather than the default camera menus. As CHDK is continually evolving, new features are[...]

CHDK will now be running in the background. Some features are enabled by default, for example, battery and memory indicators. However , most features are disabled by default. T o make changes to how CHDK operates, you start by entering <AL T> mode . <AL T> Mode When <AL T> mode is enabled the function of certain buttons on your ca[...]

History of CHDK From Stereo Data Maker site:- http://stereo.jpn.org/eng/sdm/chdk.htm : !!!!! http://stereo.jpn.org/eng/index.html During the second half of 2006, programmer ' V italyB ' studied a disassembly of the firmware update for an IXUS camera in order to understand the Canon ® firmware-update procedure. W ith that knowledge, he [...]

The A640, A700, A710, G7, IXUS700, A570 (by Rossig/MX3 ) and IXUS800 were soon supported and new video features added. Tv bracketing in continuous-shooting mode, long-exposure feature by Fingalo and A560 support followed. The first cameras to be supported were all based on the Canon ® Digic II ® processor using the VxW orks ® operating system. [...]

KAP Kite aerial photography (KAP) is a hobby and a type of photography . A camera is lifted using a kite and is triggered either remotely or automatically to take aerial photographs.

RA W notes It may be said that CHDK owes it's existence to the desire for saving RA W in RA W barren Powershot cameras. By inspired work on the Firm update procedure with these cameras, it was discovered that RA W was actually a disabled function of the original firmware, and with further genius, enabling RA W saving and other functions saw t[...]

F AQs and Facts Q. Can CHDK damage your camera " ? A. Short answer : It is unlikely , but theoretically possible. CHDK comes with no warranty for any use; you use it at your own risk.

Q. What’ s the future for CHDK ? A. There’ s no doubt that clever people will continue to develop more features, scripts, etc., and more cameras will be ported, CHDK will be refined, until it is released as v1.0, and perhaps beyond, which seems to be very close, so the future looks good for CHDK. This User Guide has been written up to May 2010[...]

Experimental development is being done on the PTP feature for CHDK cameras, this will provide computer control of a camera similar to Canon’ s EOS Utility and Remote Capture, but with CHDK capability such as remote script control.
