kept his plates fair

We Followers saw things from Whistler’s standpoint. If he etched a plate, we had to etch it almost exactly on Whistlerian lines. If Whistler kept his plates fair, ours were so fair that they could scarcely be seen. If Whistler adopted economy of means using the fewest possible lines, we became so nervous that we could scarcely touch the plate lest we should overelaborate.
