Canon Powershot users might find this interesting: :mrgreen: I would love to try it but my Camera model is not yet supported (A530)

quoted from the FAQ page:

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.

Please see the FAQ and the Firmware Usage page, as well as other pages on this wiki, for more specifics on supported cameras, details of features, scripting, downloading, etc.

A sampling of those additional features/functionality.

Main features:

* Save images in RAW format
* 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
* a higher compression movie mode, and double the maximum video file size
* exposure times as long as 65 seconds
* exposure times as little as 1/10,000 of a second
* ability to use the USB port for a remote trigger input

Additional features:

* a depth-of-field (DOF)-calculator
* File browser
* Text reader
* Calendar
* 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
