    <pre> We hired a Nikon DIX to test it out on some exhibition photography and it's come up with three file names: NEF, TIF, and JPG. I know what TIF and JPG mean, but what is NEF - is this a new format from Nikon, or is it a standard file type, and what is it's purpose? Sould we keep all three files, or can we ditch the NEF file & just keep the TIF and the JPG.

    Examples of the three image sizes & resolutions are as follows (all shot from same subject & lighting conditions):

    NEF - File size - 7.7 MB (8084216 bytes); image size 3008 x 1960; resolution 600 x 600 dpi; 12 bits/channel.

    TIF: - File size 16.9 MB (17770948 bytes); image size: 3008 x 1960; rsolution 300 x 300 dpi; 8 bits/channel.

    JPG - File size 2.0 MB (2095446 bytes); image size: 3008 x 1960; resolution: 72 x 72 dpi; 8 bits/channel.
