Hack Your Canon Digital Camera Safely with CHDK

Here’s one of my favorite mobile device hacks. And, it has nothing to do with phones. If you have one of Canon’s many digital camera models, you may be surprised to know that it can do a lot more than Canon’s firmware lets it do. The key here is that digital cameras have firmware that can be updated just like phones and other mobile devices. Canon itself provides updates now and then for various models to fix problems and, very rarely, add features.
