I have bought a 40D but cannot open my raw files in CS2. I have down loaded and tried, without success, the camera raw.8bi ver 4.2 from the Adobe web site. Apparently it is for CS3 users and not compatible with CS2. Can anyone please help? What version of camera Raw do I need in CS2 for the 40D? Before posting this question I scouted through previous questions and saw a lot of suggestions/debate without resolving my problem. The following extracts highlights my problem the best: DN Sep 21,2007;08:20p.m. Am I reading that right? I cannot update Camera Raw to read 40D images in CS2;I have to upgrade to CS3? Colin Southern Sept 21 2007;08:26 Simply convert the file to *.DNG format first-you can download the free converter from www.adobe.com Joshua Uziel Sep21,2007?08:26p.m. That seems to be the case. Camera Raw 4.0 and greater is not compatible with Photoshop CS2. Now I am totally confused as I don't have any idea what *.DNG is and which file must be converted. Also is it possible to read 4oD files in CS2?
