- Description
- 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.
- Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
