Second Curtain Sync:

With focal plane shutters, flash synchronization is normally
activated when the first shutter curtain is completely open. With
Second Curtain Sync, the 430 EZ is fired just before the second
shutter curtain starts closing at the end of the exposure. To use
Second Curtain Sync, simultaneously press the "+" and "-" buttons
(fig. 12) to display the Second Curtain Sync symbol in the
display panel.
This effect is more beneficial and noticeable at shutter speeds
slower than 1/60 where the blur of a moving subject is frozen at
the end of the exposure rather than the beginning--thus creating
a more natural-looking rendition of that moving subject.
Note:
Second Curtain Sync does not work when the camera is
set to Program mode, or when the 430 EZ is used off-
camera.
Bounce Flash:
Bounce flash illuminates the subject by turning or angling the
flash head to reflect its light off a wall, ceiling, card, etc.
Because of the A-TTL output control of the 430 EZ, there is no
need for exposure calculations or measurements when the camera is
used in an automatic mode.
When the flash head is rotated by releasing the "Bounce Latch"
(fig. 13) or lifting the flash head up, a Bounce Flash symbol
(fig. 14) will appear on the 430 EZ's display panel. Once the
camera's shutter release is partially depressed, the 430 EZ will
emi\ a 1/20 power pre-flash to determine the best shutter speed
or aperture value prior to the actual exposure.
Note: The flash coverage of the 430 EZ auto-zoom mechanism
indexes to the 50mm position although this is not displayed
on the data panel. The zoom feature can be set to a manual
position for user-set light distribution.
