Technology already made that possible, just not in the world you had
accessible! The wet darkroom permitted all that stuff too!
But I agree, Photoshop has some wonderful advantages - like being
able to see right away whether you did the thing you intended and
then being able to undo it if it turned out not to be what you
wanted, like not smelling awful, like not using up water - all the
things we all know about.
