If one of the conditions for conforming to the definition of "serious wedding photographer" is the fact that he or she does not deliver raw files, you are absolutely correct....Forget it. No serious wedding photographer will ever give you his raw files.
On the other hand, I've seen very competent work delivered in the form of raw files to paying customers who prefer to do their own computer manipulation. It is all the matter of negotiating the contract, on both sides.
(FWIW, I've heard that repeat print business in wedding photography has dwindled to a trickle compared to what it was in the film days. Which, if correct, makes hanging onto and archiving image files (of whatever format) much less attractive business proposition for the photographer than it used to be).
