NRW is a highly specialized raster image format that uses the Nikon Coolpix digital camera from the renowned Japanese manufacturer Nikon, as well as selected models of Nokia mobile phones. Full name - Nikon Raw Image File. The format is designed to create uncompressed digital photos in RAW format when shooting with a camera of a specified manufacturer. To open files of this format, special programs are needed, and to convert to another, more common, format, special converter programs are needed. The advantage of NRW files in saving data is in the version that the camera sensor detected; there is no compression or color correction.
GIF is one of the most common raster image formats. Its name is an abbreviation for Graphics Interchange Format File. The developer is the CompuServe organization. A feature of this particular image format is its ability to support the animation function. You can edit animated GIFs in different programs (for example, Easy GIF Animator). Animation is achieved due to the fact that a file of this format carries in itself in a certain sequence several raster images at once. With a depth of up to 256 colors, significant data compression in GIF files is possible without loss of quality.
