Course contents

The practice of still-photography and cinematography is becoming more a branch of applied science and less an empirical craft; therefore, it is increasingly necessary to base the practice on a thorough understanding of photographic materials and processes rather than on rule-of-thumb methods. In a sense, the craft has been simplified by advances in the production of more satisfactory new materials and equipment and the development of new and better methods, but the very diversity of these materials and the tremendously increased scope of modern photography and cinematography combine to demand a more thorough knowledge of fundamentals than was formerly necessary.

Schedule of assignments:

1/ Light concept – electromagnetic spectrum, visible part of the spectrum, light generation, natural phenomena – sunlight, skylight, man-made sources, incandescence, luminescence.

2/ Measurament of light quality – color temperature, limitation to color temperature, the technical specification of light sources – tungsten, flashtubes, fluorescent.

3/ Filters – general filter information- glass filters, gelatin filters, acetate filters, filters for black and white photography, filters for color photography, mired system for light source conversion.

4/ Color meters – types of color temperature meters, evaluation of color temperature with respect to photographic materials, practical tests with light sources and filters.

5/ Measurament of light intensity – light detection, light units, basis of photometry – inverse square law, cosine law, photometers – illuminance photometers, luminance photometers.

6/ Properties of objects – index of reflection, index of transmission, optical density, psychometric tone scale and its relation to indexes of reflection, average gray.

7/ Relation between object and optical image – parameters influencing illumination in the film plane, lens aperture, stop numbers, effective stop numbers, extension tubes, magnification.

8/ Calibration of photometers – calibration of luxmeters, calibration of spotmeters, useful formulas – calculation of exposure illumination.

9/ Speed systems – ASA, DIN – ISO, practical speed testing, testing objects and their properties, practical experiments.

10/ Tone reproduction – negative material influence, positive material influence, transfer and reproduction quadrants, the effect of flare, details in shadow and highlights, useful latitude, used latitude.

11/ Setting the correct exposure – methods used for setting the correct exposure with illumination meters and luminance meters, relation of luminance to scale of indexes of reflection.

12/ Practical testing – measurament with different types of photometers, testing of photometers, analysis of practical tests.

Assessment methods and criteria

Minimum required attendance to the class is + 70%

Central to the course is how well students can apply the material presented in practice, tackle practical problems connected with measurement of light and set the correct exposure.

The course grade will be calculated as follows:

Midterm test -30%

Final test -30%

Discussion -30%

Regular and active participation in classes - 10%
