What is CHDK?

CHDK is a unique software application developed by enthusiasts that enables extra features for ported Canon™ Powershot™ cameras.

* Shutter-priority (Tv) exposure - via shutter value override feature

* Multi-language Interface - CHDK supports many languages
* Custom CHDK User Menu - for instant recall of up to 10 favorite functions
* Scripts execution - including intervalometer, motion detection, etc
* And many others.

How is all this possible?

Firstly, by the the skill, persistence, and generosity of the Developers, and other contributors to the CHDK project.

Secondly, in the same way that your computer hardware runs an operating system, such as Windows, Mac OS, or Linux, your Canon camera also has an operating system in it. And in the same way that your OS runs Photoshop or Zoombrowser on your computer, the OS in your camera is also able to run programs such as CHDK.

Does CHDK permanently alter the camera?

No. CHDK is simply software. Just like your computer, when the camera is turned off all the software disappears from memory until it is turned on again and CHDK is loaded again. Also like some software, there is an option to automatically start CHDK when the camera starts.

How does CHDK get on the camera?

In the same way that you install Photoshop or Zoombrowser onto your computer (by copying the software onto your hard drive,) CHDK is installed by copying the CHDK software onto the camera’s 'hard drive'...the SD flash memory card.

How does CHDK software get copied to the flash card?

You can copy software to your SD flash card using a file manager such as Windows Explorer. A card reader must be used to connect the SD flash card to your computer. Once connected, the SD flash card appears like any other hard drive on the computer. Your printer may contain a usable card reader. Card readers are fairly inexpensive, and can simplify transferring of files, although given the right file naming, files can be transferred via USB. See:- Raw Parameters, and DNG visible via USB.
