Close-Up Flash Photography.24; Second-Curtain Synchronization.24 - Canon Speedlite 540EZ Manual

5. Close-up Flash Photography
The 540EZ's flash head can be angled downward 7° for better flash cov¬
erage in close-up shooting situations. With the flash head in the 7° down¬
ward position, sufficient flash coverage is provided in the lower part of the
scene when shooting at close distances.
(
7~ .. > When the flash head is angled 7°
TTL Zoom 5u mm downward, the 7° downward posi-
tion indicator is displayed in the
___LCD panel.
MODE
SEL/SET ZOOM
The 7° downward position is effec¬
tive only for close shooting dis¬
tances of 0.5 ~ 2m / 1.7 - 6.6ft with
the flash head directed straight for¬
ward.
When the shutter button is pressed
halfway, the 0.5 - 2m / 1.7 - 6.6ft
coupling distance bar indicators light
in the LCD panel.
Coupling distance bar segments to
the right of the 2m / 6.6ft indicator
and to the left of the closest dis¬
tance indicator blink in the display to
indicate that the flash head is in the
close-distance shooting position.
If the coupling distance falls outside
of the 0.5 - 2m / 1.7 ~ 6.6ft range,
all of the coupling distance bar seg¬
ments blink to warn you that the
shooting distance is inappropriate
for the flash head setting.

6. Second-Curtain Synchronization
When the 540EZ is used with an EOS camera, you can select whether to
have the flash fire as soon as the shutter opens (first-curtain sync) or
immediately before the shutter closes (second-curtain sync).
When using a slow shutter speed with a moving subject, second-curtain
synchronization will provide a more natural effect because the flash expo¬
sure occurs at the end of the subject movement rather than at the begin¬
ning, providing a "trailing blur" effect that emphasizes motion.
Second-curtain sync First-curtain sync
Second-curtain sync flash photography is not available in Full Auto (I.I) c
Programmed Image Control (PIC) modes.
Second-curtain sync cannot be combined with stroboscopic flash operation.
Setting the camera's shooting mode to bulb makes it easier to produce effective
second-curtain sync flash shots.
