Hi to all working on the SX110IS porting, and good luck. Unfortunately I am a newbie too, so of little help with the nitty-gritty of programming and too far off learning the lingo. I too am anxious to know how to get RAW capture from my new toy (as it's all I use with my SLR) but it's looking like I wont find out until after the holiday I bought it for... never mind.
On another note, I signed up to give notice to 'the1who' and anyone else here anxious to go remote with shutter control -
I found a bit of freeware called 'cam4you'. Currently version 2.00 build0.
Although it's not yet on their list, it does now support the SX110IS. It gives a basic liveview and zoom, plus manual controls for both stills and video capture. There is no guide as yet, but a swift look around pays off. There is timestep programming and motion sensoring, so much to play with, still doing just that myself! Link below:
