Physical and technological approaches to systemic film moistening

Abstract

This article discusses the physical and technological approaches to systemic film moistening. The features of storage and operation of film in various conditions are considered. A number of features and facts are presented that affect the organization of both systemic humidification and the maintenance of long-term storage of film materials on analog media. The article presents the main factors that affect the quality of the working surface of 35 mm and 16 mm film: the specifics of the composition of the film; the effects of a temporary, natural and technological nature on motion pictures; sophisticated technology for servicing analog film projectors, rewinding devices and film checking facilities. The analysis of the sequence of manipulations of technological equipment and chemical compositions for stable operation without gusts, drying and burnout of film materials is carried out. The article gives the physicochemical content of work on the stages of film moistening, taking into account the specifics of the applied filmostatic liquids. In the step-by-step process of moistening, after the end of each stage, the main results obtained are assessed by visual comparison of the image projections, followed by the digitization of the image and the correction of the result obtained in graphic editors. To eliminate artifacts, scratches and other elements of entropy, the authors recommend using neural network approaches for working with film materials.
