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.
Format used for saving large Photoshop documents over 30,000 by 30,000 pixels in size; supports images up to 300,000 by 300,000 pixels; to enable .psb support, check the "Enable Large Document Format" within the File Handling pane of the Photoshop Preferences window
