EXPOSURE METERING

EXPOSURE METERING METHODS

The Leica S provides three diﬀerent exposure metering methods:

Setting the function

1. In the

CAMERA menu (see p. 16/26), select Exposure Metering (5.3), and

2. then, in the associated submenu, the desired option.

Spot metering -

For spot metering, only the center of the image ﬁeld is detected and evaluat-

ed. The area is indicated by circle in the center of the focusing screen.

Center-weighted metering -

This metering method takes account of the entire image ﬁeld, although the

parts of the subject situated in the center have more inﬂuence on the expo-

sure value calculation than the areas at the margins.

Multiple ﬁeld metering -

This metering method is based on recording ﬁve metered values. One value

is determined in a ﬁeld in the center of the image, the other four in the sur-

rounding ﬁelds. The ﬁve metered values are used for calculation in an algo-

rithm appropriate to the situation, resulting in an exposure value adjusted to

correctly reproduce the assumed main subject.

Not all focusing screen versions have this circle (see p. 66).

METERING MEMORY LOCK

The Leica S records

- diﬀerent parts of the subject, depending on the metering method, for expo-

sure metering, and gives them a diﬀerent weighting,

- only part of the subject for autofocus metering (see p. 37).

The values are initially always stored using the shutter release button (1.1,

see p. 36). Depending on the menu settings, the joystick (1.18) can also be

used to retain one of the (stored) settings when the shutter release button is

released.

In contrast to the shutter release button, this stores the relevant settings not

just for one picture but for as long as it is held down, i.e. possibly for several

pictures.

The

AE-/AF-Lock menu item (Automatic Exposure / Autofocus) is used to

select the assignment of the functions.

Storing with the shutter release button

1. Aim the circle in the viewﬁnder at the area to be metered.

2. Press the shutter release button (1.1) to its 2nd pressure point. As long as

the button is held at this point, the value is stored.

3. In the automatic exposure modes

, and (see p. 44/45) the light

balance (2.6) appears and indicates the variation from the stored metered

value.

If the aperture value or the shutter speed is changed during this time, the

other value adjusts accordingly and is displayed.

4. While holding down the shutter release button, decide on the ﬁnal compo-

sition and

5. release the shutter.

Metering memory lock is canceled when the shutter release button is let go

from the pressure point.
