I stumbled across a website that offers methods and non-permament, OS modifying software to open up a bunch of new functionality to Canon's wide variety of PnS cameras. I have two, SX710HS & an old D10. These two units primarily live in my motorcycle jackect attached to a lanyard for shoot-on-the-go picturetaking without having to stop.
The website is CHDK - http://chdk.wikia.com/wiki/CHDK
Looks pretty interesting. Gonna have to find Windoze machine to add the file to the Fat32 formatted SC card as provided by the camera.
Have any of you tried it?
