Adobe also has a plugin called Camera Raw. But, you'd need CS2 to get support for the plugin that works with your D80.
Jim, I know Adobe Camera Raw works with Photoshop Elements3 and above. Won't that also read the D80 raw files?
Also, shouldn't the D80 come with software to read the raw files already? Of course, you'll usually want more features so you'll wind up getting another program. But to do basic correction, I'd figure Nikon would include that with the camera.
