The LCAM data has been posted to the "raw images" site at the link below, although they do appear to be processed (contrast enhanced) so you may need to wait for the PDS release for the real raw data. You can tell by looking at the images before heatshield separation or after touchdown that they have been contrast enhanced (all images were taken at similar exposure times).
