| Description | CRW is a proprietary image file format used by some Canon digital cameras. It is a raw image format that contains unprocessed data captured by the camera's image sensor. CRW files are similar to other raw formats in that they offer greater flexibility and control over image processing than other file formats like JPEG, but they require more processing and editing to produce a finished image. |
| Technical details | CRW files contain uncompressed image data from the camera's image sensor, as well as metadata about the camera settings used to capture the image. Because CRW files are not processed in-camera like JPEG files, they offer more flexibility for adjusting exposure, white balance, color balance, and other image settings during post-processing. CRW files are often converted to other more widely supported raw formats like Adobe's DNG format or TIFF for further processing in image editing software. |
