Does Platinum printing involve a contact print? I wouldn't be happy sending out a contact print of a 35mm negative.
Contact printing need not be done with in-camera negatives. It can also be done with enlarged negatives. It is the way I do it most of the time, actually, for VDBs and cyanotypes. I've made them from the in-camera film, but most of the time I enlarge them and then use the enlargements to make the contact print.
