I tried to download and install Ken Rockwell's U1 & U2 settings for the D600, but nothing happens. I went to his site, downloaded the file to my desktop, copied it to a SD card and followed his directions and saved it to my camera. Nothing changed. Couple of questions. First I formatted the card in my Nikon, file was downloaded on my Macintosh computer and directly copied to the card. Loaded into Nikon and set dial to U1 before the save. Does the file have to unzipped first? Different mode setting for saving file? Any ideas? Thanks
