Ratty Mouse: are you developing yourself, or are you having someone else do the developing and printing? The fault is definitely not in the camera. Before I did anything, I'd take a good look at the negatives. In the shadows (nearly clear areas), can you see detail in them that you can't see in the print? That suggests that the printing isn't as good as it could be. If the printer printed at too high of a contrast level, you could loose the shadow details. Before I'd change the exposure, Id verify that the negatives are the issue and not the printing.
