If your script does not work properly, try to increase the "script shoot delay" parameter, which is asmall time-delay after a shot is taken, before the next line of the script is executed. Some scripts alsomay require certain camera settings. For example the generic bracketing script: go to menu>reviewand switch it to "off". Use P, Tv, Av or M mode and activate the camera function where you want tohave bracketing. For example: Activate the focus slider when you want to have focus bracketing.Activate the exposure compensation slider in P mode when you want to have exposure bracketing, andso on. For more, go to:- Scripting notes Page 52,

and http://chdk.wikia.com/wiki/UBASIC/TutorialScratchpad

Q. May I suggest a new feature?

A. Yes you certainly can, although not every wish can be fullled. Please note that the CHDK is notable to change any standard behaviour of the camera, because it does not modify the originalrmware. CHDK can just "extend" current functionality.

Q. Whats the future for CHDK ?

A. Theres no doubt that clever people will continue to develop more features, scripts, etc., and morecameras will be ported, CHDK will be rened, until it is released as v1.0, and perhaps beyond, whichseems to be very close, so the future looks good for CHDK. This User Guide has been written up to

v0.9.7, Revision #725. For further revisions refer to the changelog.! See ;- http://chdk.wikia.com/wiki/Changelog

FAQs and FactsQ. Can CHDK damage your camera "?

A. Short answer : It is unlikely, but theoretically possible. CHDK comes with no warranty for anyuse; you use it at your own risk. CHDK is created by reverse engineering an undocumented systemthat directly controls hardware. Because of this, it is impossible to be certain that it is completelysafe.Long answer : It is very unlikely that CHDK will permanently harm your camera. There have been noreports of CHDK damaging a camera, and both the original rmware and the CHDK developers dotheir best to avoid situations where this could happen. There are at least two ways in which CHDKcould theoretically do damage:-By commanding physical hardware to do something it was not designed to do. For example, it ispossible to command the lens hardware to move when the lens is closed. (1) It is also possible to movelens hardware beyond limits allowed by Canons rmware, using scripts or overrides. See UBASIC/Scripts:_Tele-Macro-Mode (2) and Talk:UBASIC/Scripts#Tele-Super-Macro_Mode_Comments (3). It's worth noting that neither of these cases have resulted in actual damage, and both required directinput from the user.By overwriting the internal ash ROM where the Canon ! rmware is kept, rendering the camera un-bootable. Since CHDK does not ever intentionally write to internal ash, it would take an extremelyunlikely sequence of events to make this happen.If you are concerned about this, you can minimize your risk by avoiding untested development builds

(such as the autobuilds, or test builds posted on the forum) and being careful about what scripts yourun.

This image was created by stitching together 20 sets of HDRI images each created from 3 exposures.This makes for a total of 60 photographs used to create this image. I used CHDK to allow for the takingof several bracketed shutter speed exposures without re-metering in between.The nal image is 35 mega-pixels. The whole process is described here:-

Bracketing in continuous mode < Extra Photo Operations < Main Menu

Bracketing is the practice of making several exposures of a scene, with eachexposure differing from the next by predetermined steps in exposure or focussettings. Bracketing is used to easily capture a range of exposures so that thebest exposure can be selected at a later time. Bracketing is also used to createa series of exposures which will be combined using methods such as HDRprocessing.

The bracketing features are enabled when the camera drive modeis set to continuous , and custom timer with some models.

!

Set camera Custom Timer in Canon ! Menu

See Bracketing notes : Page 49.

TV bracketing value [Off, 1/3 4 Ev]Set this value to bracket via exposure time. A value of 1 willdouble or halve the exposure time for the following exposures.

! AV bracketing value [Off, 1/3 4 Ev]Set this value to bracket via aperture. A value of 1 will open orclose the aperture by 1 stop for the following exposures.

Subj. Dist. Bracket Value [0 100]Set this value to enable focus bracketing. This feature is onlyenabled during manual focus mode. This feature allows you to specify the manual focus !distancein millimeters. This value is multiplied by the Value factor below to arrive at the !nal value.

* Q. When I select the script with Func./Set, nothing happens, How do I run it?

A. From fe50 - Thanks fe50

Ok, then follow me...- power your camera on, half-press the shutter, to go to record mode- press PRINT, then press FUNC/SET- select "Load script from le", go 2 steps down to the TEST/ folder, press FUNC/SET

- select "BADPIXEL.LUA", press FUNC/SET- start the script with the SHUTTER !- wait until you see "press SET to save....."- press FUNC/SET to store the badpixel.bin automatically in the right place- press PRINT to leave the mode, press PRINT again to enter mode- press MENU, go to the "RAW parameters", enter it with FUNC/SET- enable the settings "Save RAW" , "DNG format" and "DNG le extension"- press PRINT to leave the mode again

Now RAW saving in DNG format is enabled, transfer the DNG les with a card reader...

Flash Notes

Notes on Force ash: From PhyrePhoX , for strobists: an option to manually override ash (for all cameras). even for IXUS cams. no need for a script anymore. Important: when enabled, this will notonly override ash power, but also enable the CHECK if ash is needed. in other words: your camera willuse ash even in bright sunlight and even if you disabled the ash. of course the ash will not re oncameras with popup ashes when the ash is not popped up. there are three values for the ash to be set:low, middle and POWERFUL. be careful, dont ash at home, kids.This feature more or less createdby ewavr , thanks.

For cameras with dedicated movie buttons, there is an extra menu item: Force ash only in moviemodeWhen this is checked, the Force ash feature will be enabled for taking photos when recording a video.

Note: It appears that there is another advantage by using force ash - On cameras with adjustable ashintensity there will not be a pre-ash when the intensity is set manually , which will help greatly when

using slave ashes.

As an example: Use a faster shutter and higher ISO when shooting sports, but go for a slowershutter and minimal ISO when shooting still landscapes) Method: The camera will try tomaintain lowest ISO as long as shutter speed is no-slower than user dened (more below).Custom AutoISO will kick-in whenever ISO HI/AutoISO is chosen. This allows a quick manualoverride by choosing a specic ISO value.! Example: Camera set ISO 100 at 1/8s. AutoISO congured 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 Custom Auto ISO Enable [ ] / Disable [ ]

! This is the master switch for this feature. !

Minimal Shutter Speed [Auto 1/8 -etc]! Here you have basically two options:

1.! Auto - This is for use when photographing still-life,! landscapes, etc. It will use the factors below to prevent! camera shake, but will assume the subject holds still.

2. Numerical setting - hint to the camera what the optimal shutter speed is for the subject you! are photographing.! The camera will try to use this value or a faster one as much as possible (to prevent blur),! e.g.

! 1/8s - 1/30s - Slow moving subjects.

! 1/60s - 1/125s - Kids, Pets, general movement! 1/250s - 1/1000s - Sports, Fast action

User Factor (1/FL/factor)This setting accounts for the users ability to hold the camera steady. It is based on the old rulethat your shutter speed should be no less than 1/focal-length. Start by dividing the effective focallength of the lens by the actual focal length. The answer is generally somewhere around 6. Thenincrease or reduce this amount by a self-assessed value of !your steadiness. If you think yourhands are steadier than average then decrease by 20%. If you think youre shaky then increaseby 20%.

IS Factor (Tv*factor)In determining the ISO setting, the effectiveness of the IS system will be taken into account.Use a setting of 4 if your IS is effective enough to give you a two-stop reduction in shutterspeed. Use a setting of 2 if the IS isnt very effective, or 8 if the IS is very effective.

Max ISO HI (x10)Sets the maximum HI ISO that the camera can select.

Max ISO Auto (x10)Sets the maximum Auto ISO that the camera can select.

Min ISO (x10)Sets the minimum Auto ISO that the camera can select.

Clear override values@start Enable [ ] / Disable [ ]Extra Photo Operations overrides will be cleared for the next time the camera is started.
