Metering memory-lock

Whenever you are 1. using one of the three auto-

matic exposure modes and, 2. for an individual

photograph, you do not want the main subject or

the metered average grey area to be in the cen-

ter for composition reasons, metering memory-

lock is a very easy and useful function. It is avail-

able for both center-weighted and selective

metering.

It is used as follows:

1. Aim the 7 mm circle in the viewfinder at the

area to be metered.

2. Press the shutter release (1.17) to its 2

pressure point. As long as the button remains

depressed, the value is stored. As a visual indi-

cation of this, the relevant metering method

symbol (2.3) is extinguished. If the aperture or

shutter speed is changed during this time, the

other value adjusts accordingly and is displayed.

3. While keeping the shutter release at the pres-

sure point, compose the final picture detail

and

4. release the shutter.

The storage is cancelled when the shutter release

is let go from the pressure point.

Exposure compensation

Exposure meters are calibrated to an average

grey scale value (18 % reflection), which corres-

ponds to the brightness of a normal photogra-

phic subject. It is often the case that the metered

subject area does not match these requirements

or, for a particular reason (e.g. due to a different

use or personal preference) that you want some

photographs to be slightly darker or brighter. If

this applies to a whole series of successive

photographs or an entire film, you should employ

an appropriate exposure compensation rather

than metering memory-lock, which can only ever

be carried out for a single photograph.
