Basic Photo Chemistry

Tutor:

Jiří PETERA

Synopsis:

The course focuses on the theoretical knowledge and manual skills involved in the photographic process so that students are able to take advantage of the knowledge they acquired in their next production.

In the theoretical part the students will learn about the principles of photographic record and the types of photographic materials and their processing methods.

Through practical exercises the students will draw on their theoretical knowledge to obtain manual skills in the basic processing of black and white materials and in special photographic processing methods.

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

Prerequisites:

Evaluation:

Practice: 4 black white photographs of 30 x 40 cm format (development kinetics)

Final exam: examination paper

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

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

Special photographic processing

Diffusion effects

Reducing and intensifying

Rehalogenations

Toning

Black&White reversal process

(Structure and processing of B&W reversal materials)

Colour photographic materials

Light and colour ? additive and subtractive colours

Physical principle of colour photographic record

Chemical principle of colour photographic record

Types of colour photographic materials

Negative-positive system (record principle and processing)

Colour reversal materials (record principle and processing)

Kodachrome (record principle and processing)

Colour materials based on diffusing processes

Study Objectives:

Outline and Syllabus:

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 train manual skills in the basic processing of black and white materials as well as the skills needed for special photographic processing methods.

To summarize, the students will obtain integrated knowledge about photographic processing and the ability to completely use their photographic production..
