It's also worth remembering that if you are using photography for creative (as opposed to reprographic) purposes, exactly reproducing what you saw is often very precisely not the point. And if you are going to reproduce those images on paper, a negative film (with its built in correction mask) is generally going to give you an easier time of it than dealing with a transparency (which owes at least as much of its longevity to the ease of telling a repro house 'match it' as it did to immediately being able to tell if your/ your lab's process was off target). I don't mind Velvia, but all too often it gets used in service of a kind of instantly forgettable paint-by-numbers landscapery (so much of which is reproduced in 4-colour anyway!) rather than for its inherent qualities - it can make a very interesting portrait film - once you understand that the only limitations to its use are your culturally conditioned ones learnt from self-appointed 'experts'.
