3 Setting Speedlite Functionst
302
Flash zoom (Flash coverage)
With Speedlites that have a zooming flash
head, you can set the flash coverage.
Normally, set this to [AUTO] so that the
camera will automatically set the flash
coverage to match the lens focal length.
Shutter synchronization
Normally, set this to [First-curtain
synchronization] so that the flash fires
immediately after the exposure starts.
If [Second-curtain synchronization] is set, the flash will fire right before the
shutter closes. When this is combined with a slow shutter speed, you can
create a trail of light such as from car headlights at night. With Second-curtain
synchronization, two flashes will be fired: Once when you press the shutter
button completely, and once immediately before the exposure ends.
If [High-speed synchronization] is set, the flash can be used at all shutter
speeds. This is especially effective for portraits using fill flash when you want
to give priority to the aperture setting.
Flash exposure compensation
Set flash exposure compensation if the flash
exposure of the subject does not come out
as desired.
For details, refer to the instruction manual of
the Speedlite.
