FLASH CONTROL

apply to settings and functions available in this camera and in
system-compatible flash units.

SYNC POINT

Flash exposures are lit by two light sources:
– ambient light
– Flash
Any subject elements lit primarily by the flash will almost always be
rendered in perfect focus by the short burst of light, provided the
focus is set correctly. All other subject elements in the same frame
lit by ambient light or lit from within will be rendered with varying
degrees of sharpness. Whether or not these object elements will
be rendered in sharp focus or blurred, as well as the degree of
"blurriness" depends on two interdependent factors:
– the shutter speeds
– the speed of movement of the subject elements or camera
during recording
The longer the shutter speed and the faster the motion, the greater
the difference between the two superimposed partial images.
