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 (P, T, A; 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 flash photography, the histogram cannot represent the final 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 differ slightly from that while the picture was taken.

Exposure control

The Leica X2 offers 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 1/2000s 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 differ 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.
