Setting an exposure compensation
Exposure meters are calibrated to an average grey
(18% reflection), which corresponds to the bright-
ness of a normal, i.e. average, photographic sub-
ject (for more details see the section "General
information on exposure metering” on p.106).
If the relevant subject details do not meet these
requirements, a corresponding exposure compen-
sation can be carried out.
Particularly for several shots one after the other,
e.g. if a series of shots with a slightly lower or
higher exposure is deliberately required for a
particular reason, exposure compensation is a
very useful function. In contrast to metering
memory-lock, once set it remains effective until it
is (deliberately) reset (more details of metering
memory-lock can be found in the appropriate sec-
tion on page 98).
With the LEICA M7, exposure compensations can
be set at
1
/
3
EV intervals in the range ±2 EV.
To do this:
1. Hold down the release button (30), and
2. then turn the locking dial (28) so that its
white index dot is opposite the desired
compensation value on the scale (27).
The whole range of possible compensations of
±2 EV can be used for all engraved film speeds.
Overall, the resulting extended setting range
makes it possible to use speeds from ISO 1.5/3°
to ISO 25000/45°.
Any exposure compensation set is indicated in the
camera’s viewfinder, see the table on page 81 for
details.
Note: Any exposure compensation set on the
camera influences both the metering of the
available light and the TTL flash exposure meter-
ing.
