EXPOSURE LOCK
For compositional reasons, the most important part of the subject
is often not in the center of the picture, and as a result such
important parts of the subject may be excessively light or dark.
Center-weighted metering and spot metering record predominantly
or exclusively an area in the center of the image are calibrated to
an average gray scale value.
Subjects and situations of this type can be overcome very easily
even in aperture priority mode, using metering memory lock.
Notes:
• Metering memory lock should not be used in conjunction with
multi-field metering, as in such cases selective recording of a
single subject detail is not possible.
• In conjunction with exposure lock (by pressing the shutter
release down to the first pressure point), Live View also provides
an exposure simulation feature (see p. 168).
Using the function
1. Aim at the important subject detail (with the metering field for
spot metering) or alternatively at another detail with average
brightness.
2. Pressing the shutter release down to the first pressure point
activates metering and storage. As long as the pressure point
is held, a small red dot appears in the viewfinder at the top in
the digits line for confirmation, and the exposure time no
longer changes even if the lighting conditions are different. A
dot appears between the ISO and exposure compensation
values in the monitor.
3. Keeping the shutter release pressed, move the camera to
capture the final trimming,
4. The shutter can then be released using the exposure originally
determined.
Changing the aperture setting after using exposure lock has no
effect on the shutter speed, and will lead to an incorrect exposure.
Exposure lock is canceled when you remove your finger from the
shutter release pressure point.
