Course contents:

Brightness Measurement:

1/ Determining the extent of brightness with a given testing slate through the use of a luminance meter with a view to the darkest field and registering onto the slate the relative values of the other fields.

2/ Using a luminance meter for creating the relative luminance of two grey plates VÚZORT for attaining the brightness extent 1:40 and 1:100. Using a illuminometer to measure the resultant relative light.

3/ Establishing material exposure with 21 DIN sensitivity and based on luminance measurements, gauging the first white field on the VÚZORT slate when lighting at 1280lx, and the second at 640lx, the third at 320lx and the black field at 160lx.

4/ On a given surface and with a filter determine using a luminance meter, reflecting agents and procedures.

5/ Gauging on a densitometer a given negative wedge-stock and measuring a recorded grey slate. Considering that the given material has a sensitivity given by the producer in DIN, determine using measurement values the correct practical sensitivity.

6/ On the process graph, mark the position of individual fields of the grey slate and establish their reflective value.

Illuminometer measurements:

1/ Calculate and mark onto Plate 1 for a given light source the distance which the prescribed light value attains.

2/ With a freely selected light source of greater than 1kW, determine using a illuminometer its light intensity, calculate its distance which the light attains with the prescribed value and enter it onto the slate. Check the calculations with experimental measurements and enter them on the slate.

3/ Supply the graphic relationships of the lighting measurement values for the values calculated from a characteristic gradient. Determine, for a given photoelectric device recalculation agents of the measurement values for the true lighting intensity.

4/ Determine the lighting exposure surface for the conditions for recording on ???DIN sensitive material in a 2.8 shutter and 25r/s frequency.

5/ For 3 given filters determine using an illuminometer their factors and optical density - /slate 3/.

6/ For given light and illuminometers check the gauge constant. Enter the result to Slate 4.

7/ Determine using a light meter the correct exposure slate with reflective agent o.36 on a material with 21 DIN sensitivity. Enter onto Slate 5 the measurement values and corrected exposure values.
