Flash exposure compensation
In the case of major differences in brightness and/or distance between the subject
parts in the image field (especially between the main subject and the background),
a manual flash exposure compensation may be advised to ensure the
correct exposure of your main subject. Explanation:
The TTL control of the cameras (excluding LEICA MP) as well as the automatic
flash exposure system of flash units is adjusted to a reflection factor of 25 %
(the average reflection factor of flash subjects). A dark background, which
absorbs too much light, or a bright background, which reflects strongly (e.g.
backlit shots) can lead to over or under exposure of the subject.
To counteract this effect, the flash exposure can be manually adjusted to the
photographic situation with a compensation value. On the LEICA SF 58, in the
TTL and automatic flash mode, manual compensation factors for the flash
exposure from -3 EV (f-stops) to +3 EV (f-stops) can be set in 1/3 step increments.
The level of the compensation value depends on the contrast between the subject
and the image background:
Dark subject in front of a bright background:
Positive compensation value
Bright subject in front of a dark background:
Negative compensation value

Setting the function (see also “Menu navigation / setting the functions”, p. 46)
1. In the exposure parameter menu
(EV= exposure value; f-stops) and
2. there the desired value.
Note:
Set
, select the menu item “EV”
When setting the flash exposure compensation, the range indication (2.5) on
the monitor of the flash unit can change (the more powerful illumination occurring
with a plus compensation can only be produced up to a shorter distance;
conversely, the weaker with a minus compensation also at a greater distance).
