I am having big problems opening .CR2 files from my Canon 550D.
I have got Photoshop CS3 and Elements 8, and downloaded Camera Raw 5.7 and installed it both automatically and manually. In case it may not work with CS3 I have also downloaded the trial version of Photoshop CS5.
However I still get "Could not complete your request because Photoshop does not recognize this type of file" with all of these.
Any help appreciated
Camera Raw 5.7 only works on CS4. You should use DNG Converter 5.7 to convert the new camera's images for use with your old version of Photoshop.
Although CS5 is new, it contains a dated list of supported cameras due to production schedules. Your camera should be supported when Camera Raw 6.1 arrives in a few weeks. Meanwhile DNG Converter is your only option.
Great, thanks very much, once I had re-installed the camera raw 4 file the Photoshop CS3 now open the .dng conversions.
