Well, Canon has dropped the ball. You can shoot RAW with the G15, bring them into ImageBrowser EX, try to open them in DPP, but no go on any edits of any type. It's a format that DPP sees as RAW but cannot display or edit. Of course, Adobe isn't ready for these yet, and who knows when. I've verified this on 2 windows boxes, mac to follow.
How can Canon sell a camera that you cannot work with the files? Don't tell me to use the JPEGS, I would have just stuck with a crappy P&S. The hope that f1.8 and the return of macro capability are what sold the camera to me.
Grrr. Actually, double grrr to you Canon.
