Course contents

This course covers issues of photographic images as physical-chemical process in relation to the psychophisiology of visual perception. The introduction is devoted to light and radiation, photometrics, exponometrics, characteristics of vision,color vision theory and psycho-physical phenomena influencing the resulting perception. Photochemistry and the production of photographic materials of the previous history of B/W and color photography, subsequent sensitometrics and methods of assessing photographic material characteristics; densitometrics, methods of assessing photograph microstructure - graininess, resolution, sharpness and contrast transfer.

This course includes technical exercises.

Curriculum:

  1. History of photography

Camera obscura, beginning of photochemistry, Niepce, Daguerre, Talbot, Scott Archer - wet Colloid process, discovery of gelatines.

Dry tables, optical sensibilation, beginnings of color photography - direct and indirect methods.

  1. Photography photochemical fundamentals

Effect of light absorption - molecular activation, quantum yields, basic photochemical laws : Grotthuss-Draper Law, Bunsen-Roscoe Law, Einstein's law of photochemical equivalence. Latent image-crystal constrution AgHal, crystal grating, germinal sensitifiy grating faults, latent image formation theory. light-sensitive suspense preparations, the role of gelatin as a protective colloid in AgHal precipitation, the photographic emlusion „maturing“ stage, particle size and distribution, various crystal forms and compositions. Structure and characteristics of photograph material. Chemical processing of photographic layers - chemically induced oxidation reduction issue considerations, physical and chemical development manners, composition of developers for chemical developing - developing materials, alkali, conservation and regeneration materials and anti-masking materials, super-additives. Fixation. Inversion materials processing. Particular procedures. Photographic phenomena - other influential factors besides light, double-exposure phenomena, developing phenomena, hypersensitivity, latency.

  1. Sensitometry

Development of sensitometric procedures - the work of Hurter and Driffield. Sensitometry - fundamental part, sensitometry with time and intensivity modulation, light sources - their stabilization, calibration, maintenance, modulating exposure - time, intensity -/absorption, opening, fundamental requirements.

  1. Densitometry

Concept of optical density, permeation and reflective density, primary density measurement, density types - according to geometric measured volume lighting - according to the spectral nature of the measured light - according to receptor characteristic, density of color shots - as a whole, partially, supplementary, substitutive, main, adjunct - their mutual relationships, list of important densitometer types.

  1. Interpretation of sensitometer measurements

Material gradation characteristics - sensitometric characteristics, basics of density, masking, minimal and maximal density, gradient, slope, practical and sensitometric sensitivity, sensitivity criteria, color and spectrum sensitivity, sensitometric characteristics of three-layer color materials, partial characteristics.

  1. Micro-sensitometrics

Sensitive layer structure, shot development structure, structural granularity, sujective and optical, granularity measurements, light-sensitivity resolution ability measurement, sharpness, relation of resolution ability to sharpness, measuring sharpness - acutance, modulation transfer function, list of micro-sensitometric devices.
