Take a look here: http://chdk.wikia.com/wiki/Main_Page.
It’s called CHDK firmware, and it’s an open-source firmware you can put on most Canon Powershot camera’s, including the G7. It’s great! I get to do a lot of cool stuff now, like:
- Make RAW photo’s
- Create scripts, for example for making time-lapse pictures (don’t need my laptop anymore, yay!)
- Play Sokoban on my camera
It has tons more features so if you have a powershot camera be sure to check it out. Also, the site’s complicated and you have to get some quirky binary from a weird Russian page to get it, but it works o_0
