CHDK is a firmware enhancement that operates on a number of Canon Cameras. CHDK gets loaded into your camera’s memory upon bootup (either manually or automatically). It provides additional functionality beyond that currently provided by the native camera firmware.
CHDK is not a permanent firmware upgrade: you decide how it is loaded (manually or automatically) and you can always easily remove it by taking out the memory card and restarting the camera. It will start like a normal canon powershot camera. :>(
Main features:
Save images in RAW format
exposure times as little as 1/10,000 of a second
exposure times as long as 65 seconds
a higher compression movie mode, and double the maximum video file size
Ability to run “Scripts” to automate the camera
Live histogram (RGB, blended, luminance and for each RGB channel)
Zebra mode (blinking highlights and shadows to show over/under exposed areas)
An “always on” full range Battery indicator
Ability to turn off automatic dark-frame subtraction
ability to use the USB port for a remote trigger input
Additional features:
a depth-of-field (DOF)-calculator
File browser
Text reader
Calendar
Bracketing script
Some fun tools and games
Why would I want to use CHDK?
To get Raw file capability on cameras that don’t have that ability
To get the ability to use scripts
To be able to know the battery status at all times (not just when it’s about to run out of power)
You want or need any of the other enhancement features that CHDK provides
