Moving this discussion to the Adobe Camera RAW forum.
Do you have photoshop elements or photoshop?
What version of photoshop elements or photoshop?
DNG converter 5.1 was the first version that supported your camera. But it is supported in every subsequent version. So you can use the latest version (currently 7.1) as well. It is a standalone program, and comes in its own installer. All you have to do is run the installer.
I'll just add to what JimHess has said:
- You SHOULD use the very latest DNG converter released. As mentioned above, that's currently 7.1.
- You SHOULD also always use the latest Camera Raw minor version update that works with your copy of Photoshop. In the 5.x series, that would be 5.7.
The list of what versions go together is here: http://helpx.adobe.com/x-productkb/global/camera-raw-compatible-applications.html
