Well written Godfrey!
I would just add that what processing is done on RAW files is usually
not disclosed by the manufacturer. Some Nikon's cameras RAW
compression is not really lossless, it's probably lossy (though nobody
knows exactly). Some Canon's cameras have RAW files sharpened
internally without user's option or telling him. God knows about
Pentax ;-)
Good light!
