FLASH MODES
Select one of the three available operating modes.
– Automatic
– Manual
– Long-term exposure
AUTOMATIC FLASH ACTIVATION
That is the default flash mode. The flash unit will fire automatically if
poor lighting conditions would mean slower shutter speeds, which
could result in blurred images.
MANUAL FLASH ACTIVATION
This mode is suitable for backlit pictures in which the main subject
does not fill the entire frame and is in shadow, or in situations
where a fill-in flash will moderate sharp contrasts (e.g. in direct
sunlight). The flash will fire each time a picture is taken, regardless
of prevailing lighting conditions. The flash intensity depends on the
metered ambient brightness: in poor light it is the same output as in
automatic mode, with output decreasing with increasing bright-
ness. The flash will then work as a fill-in light, e.g. to light up dark
shadows in the foreground or backlit objects, and to create more
balanced overall lighting.
