I tried to upload some raw files into cs3. Ok that didn't work. Found out I need an camera raw update plug in. I 1. Downloaded 3 or 4 updates for my cam, and ps version. Still didn't open. 2. I downloaded a DNG converter. The dng would not open my NEF files, or even acknowledge them. *Error message said, "The source folder dose not contain any camera raw files."* 3.So I open nikon viewNX and converted them to TIFF (16 bit) files. Are these files still considered raw?
