Recommended optional programme components

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 brilliance of an object and lighting in the place of its image.

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

3/ Tone reproduction

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

characteristics, limiting influences of parasite lighting on the camera, copy influence, observational condition influence, establishing the extent of

luminence of a scene, exposure extent - maximal, usable, used and its limitations, concept „exposure elasticity“.

4/ Subjective percepton of luminence structure - scales of factors of reflection and their relation to the concepts of white, grey and black, significance

and placement of scales on the luminence meter calculator.

5/ Practical exponometric methods.

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

establishing practical sensitivity, checking exposure filter factors, measuring luminence extent, the scene and reflection of the recorded surface,

measurement in a studio and in exteriors, effective shots, 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, test tables for resolution

skills, still image and size of 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.
