In digital photography, the Camera Image File Format (CIFF) file format is a raw image format designed by Canon, and also used as a container format to store metadata in APP0 of JPEG images.{{cite web |url=http://owl.phy.queensu.ca/~phil/exiftool/TagNames/CanonRaw.html |title=CanonRaw Tags |author=Phil Harvey |date=September 6, 2010 |work=ExifTool |access-date=18 October 2011 |archive-date=2 October 2011 |archive-url=https://web.archive.org/web/20111002212518/http://owl.phy.queensu.ca/~phil/exiftool/TagNames/CanonRaw.html |url-status=live }} Its specification was released on February 12, 1997.[http://xyrion.org/ciff/CIFFspecV1R04.pdf "CIFF Specification on Image Data File Version : 1.0 revision 4"] {{Webarchive|url=https://web.archive.org/web/20081230095207/http://xyrion.org/ciff/CIFFspecV1R04.pdf# |date=2008-12-30 }}.

The CIFF standard consists of two parts, CIFF Specification on Image Data File (last revision: version 1.0 revision 4, dated 24 December 1997) and CIFF Specification on File/Directory organization and File Handling Protocol (last revision: version 1.0 revision 3, dated 9 February 1998). The format was developed and maintained by Canon with input from the CIFF Forum. The format is no longer used by Canon, having been superseded by the CR2 file format.
