Some Master Cabinet Makers used to send their finely crafted Woodwork to the Master French Polisher: that was in my Grandfather's day . . . he was a Master Cabinet Maker of Fine Furniture and that's what he did.
Maybe the modern Master Cabinet Makers now do the French Polishing themself: I don't know.
But I do know when I make a Photograph with my digital cameras, that I no longer send my negatives to the Photo Lab for the Master Darkroom Technician to create the prints under my instruction . . .
