On the bright beach of Acapulco the exposu-
re value was determined by moving the
camera to the right and metering outside the
range of the subject area. The area which was
metered contained reed huts, palm trees,
deckchairs and people, i.e. an even
distribution of light and dark details.
If such substitute measurements are not
possible, exposure metering should be car-
ried out on the light details, for example, the
light sand on the beach or in the desert, the
whitewashed walls in a Greek village or the
snow on the run of a ski slope, and the value
then corrected accordingly.
Opening the aperture by two stops corrects the
exposure value for purely white details, as
does multiplying the shutter speed by 4 (e.g.
1/125 s instead of 1/500 s). For light-coloured
details such as sand, it is sufficient to open the
aperture by one stop or double the shutter
speed.
In sunny snowscapes the correct exposure for
the areas of sunlight can be determined by
metering in the shade. In this case no cor-
rection need be made.
For photographs of spotlit subjects, when
many details of the subject are in the shadow,
or for predominantly dark subjects such as
steam engines or black fields of lava, small
