One of the things I enjoy most about consulting at newspapers are the great tips I pick up from inventive digital photojournalists. One of the handiest is this: place a cheat sheet of the most often referred to Nikon D1 Custom Settings inside the LCD screen cap (as shown below) for quick reference.
There are 31 Custom Settings in all; I've selected the top 10 and laid them out in a downloadable PDF cheat sheet. Feel free to print, trim and attach the cheat sheet to your D1's LCD screen cover. Note that a great inkjet or laser printer will almost certainly be required to render the teeny type legibly.
