Anotace:

The course is aimed at the theoretical knowledge and manual skills concerning the photographic process so the students are able to take advantage of obtained knowledge for their next production.

In the theoretical part the students will be acquainted with the principle of photographic record and types of phot. materials and their processing methods.

In practical exercises the students will resume their theoretical knowledge to obtain manual skills in the basic processing of black and white materials as well as skill at special photographic processing methods.

In sum, the students will obtain integrated knowledge about photographic process and they will be able to use their photographic production fully.

List of topics for the final exam:

Photographic materials

Principle of photographic record due to silver halide

(The role of silver halide; theory of latent image, basic principles of processing, photochemical laws (Grotthus-Draper l., Bunsen-Roscoe l., Einstein l., Schwarzschild effect)

Photographic emulsion - the collection of AgHal micro crystals (influence of micro-crystals on sensitivity, granularity, contrast; improving sensitivity-granularity ratio due to new types of emulsion grains: T-grains, shell-core grains, epitaxial grains)

Production of photographic emulsion

Optical sensitation

Processing of photographic materials

Black&White photographic materials

Chemical development (principle of chem. development, develop. agents, composition of developing solution).

Physical development (principle of physic. development, composition of developing solution).

Kinetics of development

Fixing (chemical principle, types of fixers)

Washing
