I am just considering that an ipad 2 has to download in my SD cards so when that away from home. Send them to my mac at home. When I shoot in raw data format that a canon.CR2 files. And I am aware that the ipad is generates a jpeg files for the displays but till I am not believe that its preserves the original raw file as well. So please confirm that Has anyone now or give some advice on the best way that to transfer the files to the mac?
