In CS6 Raw there is a problem with the new firmware released a few days ago by Canon for the 7D. Most photo mags are talking about it but apparently now there is a problem downloading files using Photoshop. Their solution is to not use Photoshop. JPEG works ok but the RAW does not. If you shoot two stop brackets the images look the same after download. One image is ok, two or three are not. Also Photoshop is downloading a file that the camera uses and should not be downloaded. If you upgrade to the new firmware you cannot go back! I know, my 7D with Photoshop will not process HDR spreads!
