Supercharge Your Canon Camera with Open-Source CHDK Firmware
Digital cameras have powers beyond what is immediately available to the user. On a standard Canon, for example, the fastest shutter speed option offered is 1/1,600 second, but the hardware can handle much more than that -- up to 1/60,000 of a second.
CHDK, the Canon Hacker's Development Kit, is an open-source software project that can be loaded on cameras using Canon's DIGIC II or DIGIC III firmware platforms. It unleashes new features including RAW file format, live histogram display, a battery readout, and the ability to run scripted actions on a camera.
CHDK does not replace the existing firmware on your Canon, so the process is completely reversible. The existing firmware stays intact, while the CHDK software is loaded on demand from an SD card.
- Unlimited Interval Shooting -- Use your camera for surveillance, or use it to shoot at precise intervals during a lunar eclipse or meteor shower.
- High-Speed Shutter -- Use this override option in the AllBest firmware to explore life's littler moments. You can also override the camera's slowest shutter speed settings to shoot exposures of a minute or longer.
- Long Exposure Intervalometer -- Take multiple long exposure shots all night, then assemble the shots into your own time lapse videos.
- Shoot better HDR pics with CHDK's auto-bracketing features.
