5.2. Camera Exposure Modes
5.2.1. Automatic mode of exposure control
Remove the cover from the camera lens. Set the camera to mode “A”. In this mode shutter speed is
controlled automatically depending on the brightness of the subject, and the values of diaphragm and
photosensitivity of film. This mode excludes exposure errors due to the inexperience of the operator.
Guide the camera through the eyepiece of viewfinder to the subject. Turn on the
camera. If expected shutter speed is between 1/30 and 16 s, the green light-
emitting diode flashed in the viewfinder: the use of a tripod is recommended (Fig.
A).
A
If the expected shutter speed is between 1/30 and 1/2000 s – average light-
emitting diode shines continuously: it is possible to use the camera hand held (Fig.
B).
Continuous glow or flashing of the green light-emitting diode indicates favorable
conditions for photographing.
B
The flashing of the upper red light-emitting diode with the continuously
luminous green indicates excess light (Fig. C).
You can photograph, but the quality of photographs can be unsatisfactory.
In this case to achieve normal exposure it is necessary either to select a larger
diaphragm number, to use a neutral light filter, or subsequently for such
conditions to use a film of lower photosensitivity.
C
The flashing of the lower red light-emitting diode with the blinking green
indicates insufficient light (Fig. D).
You can photograph, but the quality of photographs can be unsatisfactory.
In this case it is necessary either to select a smaller diaphragm number or
subsequently for such conditions to use a film of larger photosensitivity.
D
The camera is provided with a function to memorize exposure conditions of an object. This makes it
possible to make a “local” light-measurement of a small part of your subject, and use this setting for
the entire photo. Use as follows:
– Bring the camera close to that portion of the subject in such a way that it would be located in the
center of viewfinder and would occupy approximately 60% or more than the field of the viewfinder;
– Slightly press on the shutter release button (one flick) and, holding it in this position, arrange your
subject;
– Refocus the lens press the shutter release button fully to take the picture.
This function of camera makes it possible to photograph against the sun, on snow and so forth, etc..
5.2.2. Semi-automatic mode of exposure control
Semiautomatic mode makes possible the operator to select the combination of shutter speed and
diaphragm and to estimate the error of exposure with the selected combination. This mode provides
great possibilities to the qualified operator.
