Subject guarantor:

Josef PECÁK

Name of lecturer(s):

Josef PECÁK

Learning outcomes of the course unit:

Theory and practice introduce students to the fundamentals of film exponometry.

Mode of study:

Lectures are supplemented with samples and extensive image materials.

Prerequisites and co-requisites:

Intended for bachelor study students.

Course contents:

1/ Introduction - review : calculating with logarithms.

light measurements, photometric units and laws.

2/ Theory basics of exponometry

derivation of the basic relationship between the luminosity of an object and illumination in the place of its image.

derivation of the exposure relationship and calibration measuring instruments, exposure illumination.

3/ Tone reproduction

characteristics of recorded material from the viewpoint of tone reproduction, ideal reproduction

characteristics, influences of flare light, printing, viewing condition , establishing the extent of

luminance of a scene, exposure extent - maximal, usable, used and its limitations,

4/ Subjective perception of luminance structure - scales of indexes of reflection and their relation to the concepts of white, grey and black, placement of scales on the spot meter calculator.

5/ Practical exponometric methods.

measuring with a luxmeter, exposure meter and spot meter, principles of establishing the correct exposure, macro-recording, methods of

establishing practical sensitivity, checking exposure filter factors, measuring luminance extent,

measurement in a studio and in exteriors, night recordings.

6/ Exponometric aids, grey and color tables, filters, exposure tables, calculators and regulators, filter factor mutual relationship tables, recording

frequency, exposure nomograms, nomograms for macro-recording and for establishing the size of the recording field,

7/ Measuring equipment

overview of measuring equipment, controlling their characteristics, calibration of measuring equipment

8/ Evaluating the quality and some particular procedures

the influence of exposure on the quality of the recording, tracking the precision of the exposure from copy numbers, amplified induction, reducing

contrast by prelighting or extra lighting.
