Name of lecturer(s)
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.
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.
