- Description
- An NRW file is a raw image file produced by high-end Nikon COOLPIX and digital SLR cameras. It saves image data in an uncompressed format that can be processed on the camera or on a computer after the image is captured. NRF files are similar to .NEF files, but are designed to support Windows Imaging Component (WIC) functions.
- A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.
