Please post your file-naming convention so all of us can benefit from learning what works for you and why. My naming convention is designed to accommodate three files of the same image -- a NEF, a small JPEG sized for the web, and a large JPEG sized for my monitor. NEF: Mike 2008-06-19--0056.nef Small JPEG: Mike 2008-06-19--0056.jpg Large JPEG: Mike 2008-06-19--0056-L.JPG For the rare photographs that my wife shoots (hopefully they will be less and less rare), her name appears instead of mine. The next set of numbers refers to the year, month and date the shutter was released. The last four-digit number refers to the sequential number of pictures taken that day or in that folder. The "L" in the third file distinguishes the large JPEG from the small one. Notice that the extension of the Large JPEG is in uppercase letters. That visual difference helps distinguish at a glance the large JPEG from the small JPEG.
