This paper studies the application possibilities of various mathematical analytical functions to models of approximation of sigmoid sensitometric curves of photographic materials. The newly developed functions have been tested along with approximation functions taken from the literature: the former
Hydrazine and many of its derivatives have been known as developers of the photographic latent image since the publications of Andresen? .~ Furthermore, the use of hydrazines as halogen acceptors to decrease solarization in photographic emulsions has been described in the literature? This paper pres
