Can someone with a Canon XT tell me what the extension is for RAW files on their camera? The XTi uses the extension CR2 and I was wondering if it's different from the XT. I tried to use Raw Shooter Essentials but it said no RAW files were found. I thought that the RAW files were brand specific, not camera model specific. I don't have a problem buying a converter (I tried the free version from before Adobe bought it out) but there are so many to choose from (I'd like to get a trial version first). I use the Digital Photo Professional software that came with my camera but I might prefer another program. The interface is a little cumbersome with DPP.
