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.
TGA is a long-used raster graphic format. It was developed by Truevision Inc. (now Pinnacle Systems) back in 1984. It was initially used by the developer only for its own graphic adapters, but gradually gained popularity (primarily in the field of video processing and animation). Widely used in computer games, where it is used to store textures (including 3D video games). The name of the format comes from Targa Graphic. TGA files may partially contain image transparency information. They can become the main one for creating GIFs.
