Leica 18450 Digital Camera User Manual


 
THE HISTOGRAM
The histogram (2.1.13/2.2.8) shows the distribution of brightness in the pho-
tograph. In this connection, the horizontal axis corresponds to the tones from
black (left) through gray to white (right). The vertical axis corresponds to the
number of pixels in each brightness.
This form of representation allows – alongside the image itself - an additional,
quick and simple assessment of the exposure setting, both before and after
taking the picture. The histogram is particularly suitable for manual setting of
the exposure (see p. 130) or to check the automatic exposure control (

,

;
see pp. 128/129).
The histogram is available with both record and review modes (see pp. 120/142).
For record mode, select
Rec. Histogram
(3.20) in the menu, and in the sub-
menu the desired setting.
Note:
In the case of ash photography, the histogram cannot represent the nal ex-
posure, as the flash is fired after the display.
For review mode, select
Play Histogram
(3.21) in the menu, and in the sub-
menu the desired setting. Select an option with clipping to have too bright or
dark parts of the picture marked.
Notes:
• The histogram is not available in conjunction with simultaneous review of
reduced or enlarged photographs (see p. 143).
• In record mode the histogram should be understood as a „tendency display“,
and not as a representation of the exact numbers of pixels.
• When playing back a picture the histogram can dier slightly from that while
the picture was taken.
EXPOSURE CONTROL
The Leica X2 oers you a choice of four exposure modes, with which you can
adjust the camera perfectly to your preferred working method or the relevant
subject.
Both the four modes and manual settings of the shutter speed and the aperture
are selected with the respective dials (1.10/1.9).
Shutter speeds from 30s to
1
/
2000
s and apertures from 2.8 to 16 are available.
Both controls have manual setting ranges with click-stop positions – the speed
dial in whole steps and the aperture dial in 1/3-steps, and both also have an
A
-
position for automatic operation.
Shutter speeds of 1s and slower are set by first turning the shutter speed dial to
the
1+
- position, and then selecting the speed with the setting ring (1.22).
• As an indication,
(2.1.15) appears additionally.
Note:
Depending on the prevailing light conditions, the brightness of the screen
image can dier from that of the actual pictures taken. Particularly for long ex-
posures on dark subjects, the monitor image appears considerably darker than
the – correctly exposed – picture.
