I think this is why a lot of photographers love large-format cameras so much. The fact that the image is upside-down helps, rather than hinders, their compositional visualization. Plus, there really is something wonderful about the image of the world on the ground-glass. I haven't shot with a view camera for years, but I still miss that. --Mike
