The CRW file format is a type of raw image file created by Canon digital cameras. It stands for Canon Raw CIFF (Camera Image File Format), which is a proprietary file format developed by Canon for capturing all the image data recorded by the camera's sensor when a photo is taken. Unlike JPEG or other compressed image formats, CRW files contain uncompressed and unprocessed data, offering photographers a higher degree of control over image adjustments such as exposure, white balance, and color corrections during the post-processing.
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.
