With a bit of soft pencil and a bit of red creosin dye you can do a helluva lot of things faster than using a scan with computer futzing - and at
vastly less expense. I do all kinds of analog masking, esp for color work, most of it punch-and-register film techniques. But that Alan Ross low-tech approach will give you a lot of mileage in basic black and white control. I happen to enjoy true darkroom masking work. But it can really
improve prints too.
