Beyond Point-and-Shoot—Flash Mode
Set the flash mode for the optional Speedlight to TTL. At this setting, the
optional Speedlight will be controlled by the camera in response to camera
flash mode and Speedlight Opt. settings. Refer to flash-bracket and Speed-
light manuals for detailed instructions. Even if Internal Off is selected in the
Speedlight Cntrl menu, the built-in Speedlight will pop up automatically
when an optional Speedlight is used to allow control of flash output by the
camera photocell. When the built-in Speedlight is raised, do not block the
photocell with your fingers or other objects.
Before using an optional Speedlight, set the zoom head to an angle wider
than 28 mm. At smaller angles, the flash may not be able to light the entire
subject. We recommend that you take a test shot and view the results in the
monitor; if the results are not satisfactory, try zooming the camera in or ad-
justing the illuminating angle.
The COOLPIX4500 does not support power zoom or AF-assist illumination.
Use Only Nikon Flash Accessories
Use only Nikon Speedlights. Negative voltages or voltages over 250 V applied
to the camera’s sync terminal could not only prevent normal operation, but
damage the sync circuitry of the camera or flash. Before using a Nikon Speed-
light not included in the list on the previous page, contact a Nikon-authorized
service representative for more information.
Close-Ups
The built-in Speedlight may be unable to light the entire subject at distances
under 50 cm (1´8˝). Take a test picture and verify the results in the monitor.
When Lighting Is Poor
When lighting is poor and the flash is off ( ) or set to slow sync ( ), shutter
speed slows and photos may be affected by “noise” in the form of randomly-
spaced, brightly-colored pixels. At shutter speeds below
1 /
4
s, noise can be
reduced using the Noise Reduction option ( 118) in the shooting menu (P,
S, A, and M modes only).
At shutter speeds slower than 1 /
30
s, a (camera shake) icon will appear in
the monitor. Use of a tripod is recommended to prevent blurring caused by
inadvertent camera movement.
