Second-Curtain Sync Flash Photography - Canon Speedlite 300EZ Manual

5. Second-Curtain Sync Flash Photography
With focal plane shutters, flash synchroniza¬
tion is made when the first curtain is fully
open. With the Speedlite 300EZ, it is also
possible to make the flash synchronization
just before the second curtain starts run¬
ning. This is called "second-curtain sync"
and is best when a slower shutter speed is
used. (The shutter-priority AE mode is
recommended.)
When second curtain sync is used with a
moving subject and a slow shutter speed,
the light from the flash clearly illuminates
the subject for a sharp image but creates a
trailing image from ambient light for a flow¬
ing effect.
To use this function, set the sync position
selector to the right side.
