dee stands for Nikon Capture 4.1's DEE image enhancement, which I used to lighten the shadows up when I post-processed the NEF file. This shot was taken in shaded conditions actually,but I thought it looked better lightened up a bit,at when I processed it on this brand-new PC system in sRGB color space. I'm brand new to the PC,and this is my first session using a PC to run Nikon Capture,and my first experience processing in sRGB color space using Nikon Capture and NO Photoshop prior to downsizing for the web.
