I have a newer Canon Rebel T3i (600D). I want to shoot RAW, but my Photoshop is version CS4 and the latest RAW update for CS4 doesn't list my camera. The latest update that does list my camera, is for Adobe Photoshop CS5. I am not sure what my other options are? I know I can upgrade to CS5, but that definitely is not the "cheap" option. Thanks in advance!
