I don't know how traditional you want to keep it, but Ansel Adams' trilogy (The Camera, The Negative, The Print) are still some of the best (and most in-depth, if you want to read it all) introductory/intermediate/advanced books that I know. They don't treat digital, of course, so they will need to be supplemented for some more recent techniques, but they cover the basics extraordinarily well. You might get away with the first one, and then branch for digital, but even the second and third volume has the right kind of information to show how a photographic process is approached. I have several newer works, but I still return to these, even for digital.
