There is a mailing list for the discussion of and exchange of
information about the Canon proprietary RAW format (CRW). Other
formats, Canon and otherwise, also get an occasional airing.

Resources
Some of the resources I have put together with the help of others are:
- libraw.tar.gz (tar.gz format, 20k)
- A library of CIFF and CRW processing routines written by me
on an OpenBSD/i386 platform. Not complete and will need portability
changes, but does self-document a number of CRW files format features.
- CRWSPEC (Excel format) or CRWSPEC (OpenOffice format) Not yet
- A spreadsheet that documents many of the CIFF heaps used by Canon in
the CRW files for various Powershot and D-SLR cameras. Again, this is
incomplete and work in progress. Much of the information has come from
David Burren's excellent page (below) and others.
Links
Other useful places to go are:
- David Coffin's Raw Decoding project (LINK UPDATED)
- The original author of the CRW decoding code. Now also carries support for many many other RAW formats.
- David Burren's documentation of Canon's MakerNotes in EXIF
- These EXIF notes also apply to the CIFF heaps used by Canon
