CHDK

Canon CHDK alternate firmware

The CHDK is a free powerful tool that upgrades the firmware of many Canon Powershots to add some great features. We now convert almost all of the cameras supported by the CHDK, making it a very nice combination for IR shooting.

Important features that are relevant for IR photography:

RAW file support

Full manual exposure controls

Bracketting controls

Intervalometer for remote aerial photography
