It is the intention of the present paper to pick up the story at approximately the point where it was left by Dr Mees in that publication... The general over-all theory of photographic tone reproduction has been discussed many times before and it is felt, therefore, that a greater contribution to this problem can be made only by dealing with it in a rather detailed fashion. To do this, the solution of an elaborated tone reproduction diagram, illustrated by a quantitative example, will be carried through."

An example from the paper.

Returning to this diagram... Is that the ideal film curve to achieve the preferred reproduction?
