Руководство По Работе для Zorki 10
To obtain the correct exposure of the main (dark) object of photographing set smaller
value of the film sensitivity as compared with practically used one.
In this case good results are usually obtained when sensitivity decreases on one step
of the sensitivity scale. For example, when photographing on the film of 80 ASA unils
sensitivity, set 40 ASA units on the scale.
If the film sensitivity is given in DIN grades, then, for instance, 17 DIN grades should
be set on the scale instead of the used film of 20 DIN grades.
2. The main object of photographing is brighter than the surrounding background, for
instance, when photographing an illuminated face of a person against the dark
background. When photographing without correction, this picture of a person's face
will be overexposed. In this case for obtaining the correct exposure of the main object
set the larger film sensitivity as compared with the sensitivity of the film used. In
practice there can be stronger contrasts, then the correct exposure of the main object is
correspondingly obtained by other corrections.
