SYNCHRONIZATION POINT
Flash photographs are illuminated by two light sources, the available 
ambient light and the light from the flash. The time at which the flash 
is fired normally determines where the parts of the subject illumi-
nated exclusively or predominantly by the flash are shown in the 
image field.
The conventional flash firing point at the beginning of the exposure 
can lead to apparent contradictions, e.g. a vehicle being "overtaken" 
by the light trail from its own tail lights.
The Leica X Vario allows you to choose between this conventional 
flash firing point and the end of the exposure:
Select 
Flash Sync
 
in the menu, and the desired setting in the 
submenu
In the example cited, the light trail from the tail lights then follows the 
vehicle as expected. This flash technique gives a more natural im–
pression of movement and dynamics.
Note:
When using the flash with faster shutter speeds, in terms of the image 
there is no difference, or only for rapid movements, between the two 
flash firing points.
FLASH EXPOSURE COMPENSATION
This function can be used to selectively reduce or strengthen the 
flash exposure regardless of the exposure of the available light, e.g. in 
a picture taken outside in the evening, to lighten the face of a person 
in the foreground while retaining the lighting atmosphere.
1. 
Press up / 
EV+/-
 on the direction pad (25) three times
• The corresponding scale appears.
2. 
Set the desired compensation value by pressing left / right on 
the direction pad or using the direction pad  
Values from +3 to -3EV in 
1
/
3
EV increments are available.
• The set compensation value is displayed in red on the scale.
3. 
Press the 
MENU/SET
 button (15)or the shutter button (8)  to 
save the setting
• The set compensation value appears.
Notes:
• Brighter flash illumination selected using a positive compensation 
requires a higher flash power, and vice versa. Therefore, flash 
exposure compensation has a more or less significant impact on 
the flash range. A positive compensation reduces the range, while 
a negative compensation increases it.
• Pressing up 
EV+/-
 on the direction pad also opens the menus for 
automatic bracketing and exposure compensation. They scroll 
through in an endless loop and can therefore be selected by re–
peatedly pressing.
• A set compensation remains active until it is reset to 
±0
 (see step 
2), i.e. after any number of pictures and even after turning off the 
camera.
