The aim of this course is to deepen the knowledge in the field of optics, which is closely related both to shooting in specific conditions, measuring light and understanding the design of cameras. Knowledge is imparted through theoretical introductions to the various areas, practical demonstrations and studio exercises in the form of collaborative and independent work. The student is introduced to both the physical fundamentals of the field and practical demonstrations of solving specific tasks. At the same time, they will learn the possibilities and methods of using the technical equipment of the photography department, including the possibility of comparing the results obtained by analogue and digital technology.

Main topics:

1/Introduction - Characteristics of light - repetition

Theoretical part: daylight and artificial light, types of light, basic principles, possibilities of changing the character and control of light. Advantages of different systems.

2/ Introduction: basics of geometrical optics

Reflection, total reflection, bending, dispersion.

Wave optics

Interference, diffraction, resolution given by diffraction, polarization, 3D imaging

Theoretical part: basics of exponometry, photometric units, different types of measuring instruments - advantages and method of measurement and control, brightness range of a scene, exponometric aids

3- 4/ Introduction: camera, focal length, depth of field, types of lenses, exposure meter, exposure

Theoretical part: basic types of photographic equipment, their construction, advantages and uses

Practical part: working with the Sinar camera, - making

1 reproduction under glass with grey and colour wedge - demonstration of colour to black and white conversion, determination of correct exposure and demonstration of methods of developing 6x9 cm. (1 enlargement 24x30 cm)

5 - 6/ Introduction: mirrors and lenses, spherical mirrors, spherical and aspherical lenses, defects

Theoretical part: construction of lenses and their defects, resolution

Practical part: extremes of school lenses, field of view, basic tests of resolving power,

1 photograph of the surface structure of the subject with practical verification of Scheimpflug's condition of developing a 9x12 cm film. (1 enlargement 30x40 cm)

7 - 9/ Introduction: human eye and visual perception, focus and accommodation, iris, lens, retina, sensitivity, defects, light perception, binocular vision, 3D, 2D

Colours, spectral colours, additive and subtractive colour mixing, colour perception, chromaticity temperatureTheoretical part: perspective and focal length, perpendicular alignment - restitution, determining the light range of a scene in the studio

Practical part:

2 photographs of compositions of geometric objects with different lighting and perspective for one using restitution (2 enlargements 30x40 cm).

10 - 11/ Introduction: digital image

Image data, resolution, CCD and CMOS chips, image processing, displays, optical data storage, holographic memories, future of photonics

Theoretical introduction: working with Sinar camera and Sinarback 54H digital back, digital cameras, possible applications, comparison of analogue and digital photography results.

Practical part: exercises in the studio

12/ Presentation of results, selection of works to be presented in the final exam, solving specific problems, feedback.

Learning outcomes

The listener gains an expanded understanding of the physical laws of light, the operation and application of the laws of optics to the photographic process and camera design and lens function. He/she selects the appropriate technique according to the assignment. Safely navigates analog and digital photography. Immediately verifies the acquired knowledge in practice through demonstrations, practical examples and own practice.
