5.0
Owner's of the Leica Digital Camera 18450 gave it a score of 5.0 out of 5. Here's how the scores stacked up:
AUTOMATIC FLASH AND PRE-FLASH ACTIVATION
–
(to reduce „red eye” eect)
„Red eye“ effect is caused by light from the flash reflecting off the cornea
straight back to the camera and can occur when taking portrait and group pho-
tos. It is therefore best if the people being photographed do not look straight
at the camera. As the effect is worsened when the pupils are wide open in low
light conditions, when taking photographs indoors for example, you should
switch on as much room lighting as possible, so that the pupils become nar-
rower.
Due to the pre-flash, which is triggered shortly before the main flash by press-
ing the shutter release button, the pupils of the person looking at the camera
contract to reduce the „red eye effect“.
MANUAL FLASH ACTIVATION –
For backlit pictures, where your main subject does not fill the frame and is in
shadow, or in cases where you want to moderate high contrasts (e.g. in direct
sunlight) (fill-in flash).
As long as this mode is activated, the flash unit is fired for every picture,
regardless of the prevailing lighting conditions, otherwise the functioning cor-
responds exactly with those modes with automatic ash activation.
In this case, flash performance is controlled depending on the outdoor bright-
ness metered: in poor light as with the automatic mode, with increasing ambi-
ent brightness, however, with reduced output (up to a maximum of -1
2
/
3
EV).
The ash then works as a ll-in light, for example to illuminate dark shadows
in the foreground or backlit subjects, in order to obtain more balanced lighting
overall.
MANUAL FLASH AND PRE-FLASH ACTIVATION
–
For the combination of the situations and functions described most recently
above.
AUTOMATIC FLASH ACTIVATION WITH SLOWER SHUTTER
SPEEDS –
For simultaneous more appropriate (brighter) reproduction, particularly for dark
backgrounds and ash ll-in for the foreground. To minimize the risk of blur-
ring, the shutter speed is not extended beyond
1
/
30
s in the other modes with
flash activation. For pictures where the flash is used, this means that objects in
the background, which the ash cannot reach, are often badly underexposed.
To take appropriate account of the available ambient light, the longer shutter
speeds necessary in these exposure situations (up to 30s) are permitted here.
Note:
The longest shutter speed used by the camera can be determined with the
AUTO ISO Settings
settings (3.3, see p. 118).
Also depending on the
AUTO ISO Settings
settings, slower shutter speeds
may not have to be set by the camera since in such cases its priority is to raise
the ISO sensitivity first.

SHUTTER SPEEDS –
For the combination of the situations and functions described immediately
above.
