Abstract
The problem dealt with in this paper is that of finding how closely it is possible by the photographic process to produce a reproduction which will, when viewed, excite in the mind of the observer the same sensation as that resulting from the observation of the original. The treatment is divided into the main parts: the first dealing with the possibility of reproducing exactly the objective factors of the visual stimulus, and the second dealing with the subjective phase of the problem. A fairly complete system of terminology and symbols is developed in order to present more clearly the discussion, which necessarily deals with a large number of different factors. A graphic solution of the problem is given by means of which it is possible to determine quantitatively the departures from exact reproduction of both brightness and contrast in the finished print. This graphic solution is then extended to include the subjective phase and a final curve is obtained which indicates the extent to which reproduction of the subjective sensation is obtained. A practical application of the method is given, illustrating the results obtainable by the use of photographic materials, the sensitometric contrasts of which have been previously measured.
