Description NEF otherwise known as the Nikon Electronic Format is Nikon's RAW file format. RAW file formats contain minimally processed data from the image sensor of the digital camera - the metadata includes information about the lens, the settings, the camera’s identification and other data. RAW files are named so because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor. RAW image formats are intended to capture as closely as possible the characteristics of the scene to include light intensity and colours. Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF), and is the most used lossless image compression format on the Internet. PNG itself does not support animation at all. MNG is an extension to PNG that does; it was designed by members of the PNG Group.
Technical details The structure of RAW files, including the ISO standard RAW image format ISO 12234-2 follows a common pattern - a short header, camera sensor metadata, image metadata such as exposure settings, camera and lens model, date and sometimes the location. A thumbnail, a smaller JPEG file for quick viewing and the sensor image data. NEF is based on the TIFF format. PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel), and full-color non-palette-based RGB[A] images (with or without alpha channel). PNG was designed for transferring images on the Internet, not for professional-quality print graphics, and therefore does not support non-RGB color spaces such as CMYK.
