Abstract: In sensitometry, the sensitivity, contrast coefficient and fog density are generally deduced from characteristic curve graphically.The graphical method of determination of the characteristic parameters has certain limitations.In this paper, the author attempted to obtain these characteristic parameters by using mathematical models.
