I've often been impressed with the quality of images that comes from HRH's A710 and wised I could have more flexibility in processing.
There has been a Canon RAW hack for many model compacts for quite some time but I hadn't bothered to download.
Recently I've been frustrated with colour balance issues from HRH's A710 so I'm going to install the CHKD hack.
The CHKD hack works for most of canons compact range.
For anyone who's interested here is a link with information and download, The hack is quite powerful and is basically an add on (loaded from the SD card at boot up) that doesn't modify the original firmware.
There's a lot of additional information on that site, including focus stacking and scripting, as well as a number of user written scripts for download including intervalomoeter and bracketing.
There is also a link to some Open source focus stacking software Combine ZP
