,hese new features are accessed throu*h CHDK'specific menus( rather than the defaultcamera menus$ )s CHDK is continually evolvin*( new features are added as they aredeveloped$ 1pdatin* occasionally will ensure you have all the latest features for yourcamera$

Ho! is all this "ossi#le 4irstly( by the skill( persistence( and *enerosity of thedevelopers( and other contributors to the CHDK pro8ect$ #econdly( in the same way that your computer hardware runs an operatin* system( such as .indows( 7ac 3#( or 5inux( your Canon camera also has an operatin* system in it$ )nd in the same way that the 3#runs !hotoshop or 6oombrowser on your computer( the 3# in your camera is also able torun pro*rams such as CHDK$

Does CHDK "ermanentl$ alter the camera /o$ CHDK is simply software$ @ust likea computer( when the camera is turned off all the software disappears from memory untilit is turned on a*ain and CHDK is reloaded$ )lso like some software( there is an option toautomatically start CHDK when the camera starts % bootin* &$

Ho! does CHDK %et on the camera In the same way that you install !hotoshop or6oombrowser onto a computer %by copyin* the software onto your hard drive from( say( aCD& CHDK is installed by copyin* the CHDK software onto one of the cameraAs drives 'the #D flash memory card$

Ho! does CHDK soft!are %et co"ied to the flash card CHDK can be copied to your #D flash card usin* a file mana*er such as .indows :xplorer$ ) card reader is used toconnect the #D flash card to your computer$ 3nce connected( the #D flash card appears

like any other hard drive on the computer$ Bour printer may contain a usable card reader$Card readers are fairly inexpensive( and can simplify transferrin* of files( and thus files can be transferred via 1#2$ #ee also+ -aw !arameters( and D/0 visible via 1#2$

Where can CHDK soft!are #e do!nloaded Visit this .iki + !repare your #D card to learn how do to find the correct CHDK version for your camera and how to prepare your#D card to use it$ If this is your first time usin* CHDK( it is stron*ly recommended that youuse the #,ICK 1tility to download CHDK and setup your #D card$

2efore downloadin* and usin* the CHDK software( careful consideration should be *ivento the followin*+

1sually the first question is+ Can CHDK dama%e $our camera

,he short answer+ It is unlikely( but theoretically possible$ CHDK is created by reverse

en*ineerin* an undocumented system that directly controls the hardware$ 2ecause of this(it is impossible to be certain that it is completely safe$

,he lon* answer+ It is very unlikely that CHDK will permanently harm your camera$ ,herehave been no confirmed reports of CHDK dama*in* a camera( and both the ori*inalrmware and the CHDK developers use safe*uards to prevent situations where this couldhappen$ ,here is a wiki pa*e where suspected issues with CHDK can be documented +Camera failures suspected to be caused by CHDK

,here are at least two ways in which CHDK could theoretically do dama*e+

;$ 2y commandin* physical hardware to do somethin* it was not desi*ned to do$ 4orexample( it is possible to command the lens hardware to move when the lens is

closed$ It is also possible to move lens hardware beyond limits allowed by CanonEsrmware( usin* scripts( or overrides$ 4or an example of this( see ,ele'#uper'7acro7ode Comments $

$ 2y overwritin* the internal Fash -37 where the Canon rmware is kept( renderin*the camera un'bootable$ #ince CHDK is never intended to write directly to internalFash( it would take an extremely unlikely sequence of events for this to happen$

It is worth notin* that neither of these cases has resulted in actual dama*e( and both wouldrequire direct input from the user$ If you are concerned about this( the risk can beminimi9ed by avoidin* untested developmental builds %such as test builds posted on theforum& and bein* selective about what scripts you run$

ensurin* a defined level of quality re*ardless ofhow much data that level requires$

Note 1 : From owners reports of testing Quality overrides, it isevident that settings above the standard Canon setting gain littleif any higher quality. However file sizes will increasesignificantly. Lower settings will lose little in quality but willreduce file size.

Note 2 : Bitrate control is not available on all a cameras. If notavailable, the options will be Quality and Default. Bitrate and

Quality settings that are set too high can cause memory bufferoverload, and stop recording, a red ! will show on the OSD. Also -a low quality setting, or near to full/fragmented SD cards, canhave an effect on these settings.
