NEF (Nikon Electronic Format) is a raw image file format developed by Nikon for its range of cameras. NEF files can be stored in the camera’s memory card in either lossless compressed or uncompressed form. Also, a NEF file is based on TIFF and can be opened on Windows computers after installing Microsoft Camera Codec Pack.

BMP, also called a bitmap image, is a raster image file format developed by Microsoft Corporation for its Windows operating system. Typically, BMP is used to save bitmap digital images in a display device and can save two-dimensional photos in monochrome and color. Although most BMP files have significant file sizes because of lack of data compression, they can be compressed losslessly via algorithms like ZIP.
