The file is based on the TIFF specifications, which means it’s large, uncompressed, and high-quality.
Canon isn’t the only one that uses CR2 files. Poser character rigging files have the CR2 extension, as well.
CR2 files aren’t ready to view as JPEG images are, but the benefit is that you can make adjustments in post-processing, such as the white balance or exposure, without losing photo quality.
