Nikon Electronic Format is Nikon's RAW digital image format for DSLR cameras. It is a close relative to TIFF, and has a standard TIFF header. NEF files are usually big-endian, with the exception of files from the Coolpix 5700, which were little-endian. Data can be either 12- or 14-bit (from 2005's D200 onwards), and depending on the camera may be uncompressed, losslessly compressed, or lossily compressed.
