I've noticed when cropping images in Aperture, that when I set the crop aspect ratio to 3:2, that the maximum crop area still has a section (not sure how many pixels) on one side (in a landscape photo) that is left over and will be cropped out. This seems to indicate that the 3:2 images coming out of the camera are not actually 3:2 (although they may be close). Is this a problem with RAW only? Or Aperture only? I don't notice this problem with my 5DM3 in Aperture.
