Features
Overview: The Nikon Speedlight SB-910 flash has been optimized for use
with CLS-compatible (Creative Lighting System) digital SLR (Nikon FX/DX format) cameras. It can also be used
with i-TTL-compatible Coolpix cameras, such as the P7100, P7000, and P6000. Non-CLS-compatible
cameras can use the flash with limited features. The flash unit comes with a
soft zippered storage case.
Creative Lighting System (CLS):
Nikon's Creative Lighting
System (CLS) offers additional flash shooting possibilities with
digital cameras by taking advantage of a camera's digital communication
capabilities. Some CLS features available on the SB-910 include switching
illumination patterns, multi-area AF-assist illuminator, i-TTL balanced
fill-flash, image area selection, flash value lock, flash color information
communications, auto FP high-speed sync, advanced wireless lighting, and
firmware update capability. CLS is available only when the SB-910 is used with compatible
Nikon cameras with CLS.
LCD Screen:
The LCD screen provides large, easy-to-read graphics and mode indicators, such
as Flash Mode, ISO sensitivity, Effective flash output distance range, DX or FX
format, zoom head position, aperture f-number, functions assigned to function
buttons, and in indication that the flash is connected to a CLS-compatible
camera.
Adjustable Flash Head:
The flash head can be tilted from -7° to +90° and rotated horizontally 180° to
the left or right, enabling bounce flash or close-up flash
photography.
Function Buttons: The SB-910 has three function buttons that
allow you to assign a function or setting for each. The buttons are located just
below the LCD screen, with an icon for the assigned function for each displayed
on the screen.
Flash Exposure Control: The SB-910 is compatible with numerous flash
exposure controls, as set by the camera:
- Auto FP High-Speed Sync: Auto FP High Speed sync is automatically
set when the shutter speed exceeds the camera's sync shutter speed.
- Flash Value Lock: You can lock in the appropriate flash exposure,
while keeping the subject illumination constant even if you can't change the
composition.
- Slow Sync Flash: The flash is controlled at a slow shutter speed
to obtain the correct exposure for both the main subject and the background
in low-light situation or at night. A tripod is recommended to prevent
camera shake.
- Red-Eye Reduction: To prevent
the center of your subject's eyes from appearing red in color pictures, the
SB-910 fires three flashes at reduced output just before the picture is taken.
Note: You can combine this flash with the slow-sync flash (tripod recommended).
- Rear-curtain/Front Curtain Sync:
When using slow shutter speeds and shooting fast moving objects, rear curtain
sync creates a picture in which the blur of the subject appears behind the
subject. With front-curtain sync, the blur occurs in front of the subject.
Batteries: The SB-910 requires 4 "AA"-sized batteries, and can use
any of the following types of batteries: Alkaline (1.5V), Lithium (1.5V), and Ni-MH (rechargeable, 1.2V).
Standby Function: If the SB-910 and camera are not being
used, the standby function will automatically activate after a set amount of
time, switching the SB-910 to standby mode to conserve battery power. You can
set the standby function to Auto (standby activates when the camera's exposure
meter is turned off), 40 seconds, 80 seconds, 160 seconds, 300 seconds, or function canceled.
Repeating Flash Mode: The SB-910's repeating flash mode
fires repeatedly during a single exposure, creating stroboscopic multiple
exposure effects.
Light Distribution Patterns: Typical flash photography
illuminates the center of the image more than the edges. You can choose from
three types of illumination patterns with different light falloff at the edges:
Standard, Even, or Center-weighted.
Power Zoom Function: The SB-910 automatically adjusts the zoom head
position to match the lens focal length.
Multiple Flash Units: The SB-910 can not only operate as a
hot shoe-mounted Speedlight, but can also function as a master or remote unit
within a wireless multi-flash setup. There are up to four channel options and up
to three remote groups for configuring the SB-910 or other Speedlights like the
SB-900, SB-700, or SB-R200.
Built-in Accessories: The flash has a built-in wide panel
and bounce card that are stored above the flash panel. When taking close-up
photographs, the wide panel covers the flash panel to diffuse the light to
prevent overexposure. The white bounce card is used with 90° bounce flash to
make a portrait subject's eyes look more vibrant by reflecting the light in
them.
Supplied Accessories: Included with the SB-910 are the following
accessories:
- Speedlight Stand (AS-21): provides a stable placement
for the flash when you want to use it as a remote flash unit
- Diffusion Dome (SW-13H): diffuses the light creating
extremely soft light with virtually no shadows
- Incandescent Filter (SZ-2TN): balances the color of light from
the flash to match that of incandescent or tungsten lighting
- Fluorescent Filter (SZ-2FL): balances the color of light from the
flash to match that of fluorescent lighting
