Canon Digital Photo Professional writes VRD (Recipe Data) information as a trailer record to JPEG, TIFF, CRW and CR2 images, or as stand-alone VRD or DR4 files. The tags listed below represent information found in these records. The complete VRD/DR4 data record may be accessed as a block using the Extra 'CanonVRD' or 'CanonDR4' tag, but this tag is not extracted or copied unless specified explicitly.
