Upgrade your Canon Camera with CHDK

There's a really good chance that most of you are already familiar with CHDK, but if you're not - you should definitely give it a shot.

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.

Basically it takes your crappy camera and stuffs in a bagload of features that're usually found in much much more expensive ones (and some not in any!) Sounds good? I can assure you would be extremely stupid not to try it. It's amazing the things you can do with an old busted point and shoot with the enhanced features. (including and not limited to shutter speed control, custom ISO settings, ability to run scripts,games,your momma on your camera, flash sync, USB cable remote trigger, live histograms,grids, SHOOTING IN RAW.. and MANY many more)

The best part is it's free, and completely (unless you're really stupid) harmless. You'll love those long exposure shots especially if you're a star gazer like me. My friend Keyolhubey has posted a few time lapse video's he did with his Canon A530 using an intervalometer script.

head on over to CHDK and get started now. It's as easy as grabbing the proper firmware image and putting it on your camera's memory card. How can I tell?!

Q. How can I get the original firmware version number of my camera?

A. To get the version number, you need to:

  • create a file called ver.req in the root directory of your SD card. Be sure to save it as all files and not text. It might be necessary to create the file name explicitly in upper case. e.g. VER.REQ
  • IMPORTANT: Note that it is spelled ver.req, as in VERsion REQuest, that Q is NOT a G, Type it correctly!!!
  • switch on the camera in playback mode and wait for the main screen (don't switch on in rec mode and change to playback later)
  • press the
  • set+disp. buttons together (press set first, hold it down, then press disp.).

You will see a string like Firmware Ver GM1.00E. The 1.00E part is the firmware version.

ver.req is just an empty dummy file.
