ABSTRACT. The disbalansc of the theory and experimentally established properties of the silver photographic materials was considered and a conclusion on existence at least three mechanisms of the latent image speck formation wasdrown: conventional Gerny-Mott mechanism and two another ones - vibrational and dislocational. The experimental verification of the vibrational mechanism was fulfilled with the impulse laser optoacoustic method on the photographic materials under careful control. The period of latent image speck formation found to be as short as 2*10^8 sec^-1. No evidence of the electron-hole pairs generation was established under experimental conditions. The mechanism of the optoacoustic effect was purely thermal.
