With respect, I say: If you have to ask . . .no one here can possibly explain it to you in a way that you will understand. It is a little bit like the "why" of sailing or backpacking. To come back to large format photography . . .why use film today? Why do folks use wet-plate technology or any other home-brewed technique like Platinum/Paladium, Albumin pr even Daguerreotype?
