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.
JPEG is the most common and popular bitmap format. The form got its name from the name of the organization-developer Joint Photographic Experts Group. Files of this format are used today in all digital cameras and cameras. They have a good compression ratio and support 24-bit color depth. Since such compression significantly reduces image size with virtually no loss of quality, JPEG format is widespread on the Internet. However, the stronger the compression, the worse the quality. In addition, the JPEG format does not support the transparency option.
