I found something interesting in Pop. Sci.


THis unlocks a bunch of features most Canon P&S and some DSLR cameras. Like:

a. Enhanced ways of recording images - you can capture still pictures in RAW format (as well as JPEG), and for video images you can have increased recording time and length (1 hour or 2 GB), and a greatly increased range of compression options.
b. Additional data displays on the LCD screen - histogram, battery life indicator, depth of field, and many more.
c. Additional photographic settings that are not available on the camera by itself - longer exposure times (up to 65 seconds), faster shutter speeds (1/25,000 sec, and faster in some cases), automatic bracketing of exposure, etc.
d. The ability for the camera to run programs ('scripts', written in a micro-version of the BASIC language) stored on the memory card - these programs allow you to set the camera to perform a sequence of operations under the control of the program. For example, a camera can be programmed to take multiple pictures for focus bracketing, or take a picture when it detects that something in the field of view moves or changes brightness.
e. The ability to take a picture, or start a program on the memory card, by sending a signal into the USB port - you can use the USB cable to take a picture remotely.
f. The ability to do a number of other more useful (and fun) things, such as act as a mini file browser for the memory card, let you play games on the LCD screen, etc.

Here is a list of models.

Currently, the CHDK program is available for Canon digital cameras of the following models:

* A450, Fw: 1.00d

* SD630 (IXUS65), Fw: 1.00a
* SD700 IS (IXUS800), Fw: 1.00b, 1.01b, (1.01a with CHDK version for 1.01b)
* SD750 (IXUS75), Fw: 1.01a, (1.01b with CHDK version for 1.01a)

* SX100 IS, Fw: 1.00c (beta)
* TX1, Fw: 1.00g, 1.01b

In theory it can be modified to support any camera based on the DIGIC II or DIGIC III platform. (How do you do this?). See Firmware Comparisons to identify which build will work for you.

If your camera model is not listed here then there is no CHDK for it at the present time!

Basicaly you have to check your firmware version, download a new version and run it off the card. From what I can tell, no changes are made in the camera itself. Here's the instructions.

Here is a link to the download.
I had some problems the first time I tried to download. I had to skip an ad or two to actually get the file.

I haven't really used this much yet, but so far it looks cool. :cool:

Let me know how it works for ya. I've got an SX100IS and the max recording of video is 3 minutes. That alone would be great to make that longer.
