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 .
! ! 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 .
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.
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 .
More keys and shortcuts: In manual focus mode - (with <AL T> ) Up – Set MF to infinity Down – to set MF distance to hyperfocal distance (based on f/stop and zoom focal-length). Left – Decrease V alue Factor , Right – Increase V alue Factor .
On-Screen Display (OSD) Map 9 3 10 2 1 5 4b 7 4a 11 6 8 1 <AL T> Mode indicator 6 Live Histogram 2 Mini Console - Current Script info. 7 RA W shots remaining Indicator 3 Battery Indicators 8 Mis.
Main Menu ! ! The Main Menu is the top-level menu from which ! all CHDK functions are enabled and customized. ! T o access the Main Menu, set the camera to ! <AL T> mode and press the Menu button. ! Like Canon’ s menus, pressing the ! FUNC.SET button will select the ! highlighted menu option.
Override shutter speed [0 – 100] <Extra Photo Operations < Main Menu TV in the OVERRIDES display in the OSD. This feature allows you to override the camera’ s shutter speed in all auto and manual modes with the speed you select.
• V alue factor (mm) [Of f, 1, 10, 100, 1000] F ACTOR in the OVERRIDES display in the OSD. The V alue factor is used to enable the “Override Subj. Dist V alu” (OSDV), and also to quickly set the focus distance. When updating the “ Override Subj.
Bracketing in continuous mode < Extra Photo Operations < Main Menu Bracketing is the practice of making several exposures of a scene, with each exposure differing from the next by predetermined steps in exposure or focus settings.
• ISO bracketing value [0 – 100] Set this value to bracket via ISO. This value is multiplied by the V alue factor below to arrive at the final ISO value that will be used for bracketing. A value of 2, with a V alue factor of 10, will increase or decrease the ISO by 20 for following exposures.
! Example: Camera set ISO 100 at 1/8s. AutoISO configured to ISO50-400 at ! 1/15s: AutoISO will shift to ISO200 to maintain 1/15s shutter speed. ! This feature is available in all modes except for Shutter priority (Tv). It is also ! disabled in stitch assist to prevent using different settings for each panorama part.
! Enable Fast EV Switch? Enable [ • ] / Disable [ ] W arning : This feature is not properly workable on all cameras yet. See : http://chdk.setepontos.com/index.php/topic,2595.msg2421 1.html#msg2421 1 and : http://chdk.setepontos.com/index.php/topic,2501.
V ideo Parameters < Main Menu Video Mode [ Bitrate or Quality ] V ideo compression modes. ! Bitrate – dictates a constant data rate. V ideo compression (and hence, video quality) expands or contracts as necessary to maintain the data rate constant.

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.
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 di.

Curves Notes Custom Curves Enables the use of custom "curve" profiles to adjust the exposure of your RA W and JPEG images. Please read this long thread - Custom processing for JPEG (T one curve, CA ...) :- http://chdk.setepontos.com/index.php/topic,932.
Example Scripts: UltraIntervalometer (T ime Lapse) Script Code (save as "ult_intrvl.bas" to your /SCRIPTS/ folder) ---------------------------------------------------------------------------.

Flash Notes Notes on Force flash: From PhyrePhoX , for strobists: an option to manually override flash (for all cameras). even for IXUS cams. no need for a script anymore. Important: when enabled, this will not only override flash power , but also enable the CHECK if flash is needed.

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. CHDK is created by reverse engineering an undocumented system that directly controls hardware.
performed by an authorized Canon Repair Facility , would void the warranty ." ... and ... In further discussion with Canon ® about this specific hack, their response is: "If it is not Canon ® firmware the warranty would be void.
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.
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.
