This as got me very confused. I use a canon camera and the files are cr2. The pictures from last night open in PI only in grey scale. On the sd card they are in rgb, any that have been saved as raw and jpeg, the jpeg file opens in colour but not the corresponding cr2. I've transferred them directly form the camera, and on to a memory stick then open them from there, also on to a portable H/D and opened them from there. All the same result grey scale, and the jpeg are still in colour. HELP PLEASE
