Advanced wireless lighting is the use of multiple Speedlights set up for wireless remote operation. The technology of Nikon's Creative Lighting System makes multiple flash photography as easy and intuitive as flash photography with one Speedlight.
Why would you want to use multiple flash units? Simply because a single flash will illuminate a scene with what is typically called “flat light”—light that points directly at the subject. “Flat lighting” will give you a good exposure, but often it's not the best choice for flattering, dramatic or creative lighting. That's where multiple flash comes into play.
With Nikon's advanced wireless lighting system, the flash output or power levels of up to three groups (with optical control), and up to six groups (with radio control), of remote Speedlights; each group comprising of multiple Speedlights, can be controlled from the camera.
The creative possibilities of wireless remote lighting are practically limitless. No wires, formulas or calculations are necessary. Set the output of the flash units, using flash compensation, to suit the mood of the scene, or let the system automatically calculate the correct exposure.
Easily control the remote flash units, which can be located up to approximately 32 feet from the camera when the remote unit(s) is located on center, and approximately 15 to 22 feet when the remote unit is located at the periphery, with optical control. With radio control, the effective distance between the master and remote units is approximately 98 feet. You can choose the flash mode for each group of Speedlights—TTL, Manual or more—and set those instructions on the main unit.
Your off-camera Speedlights are designated in three groups: A, B, C (with optical control), and in six groups: A to F (with radio control). Each group can include one or more Speedlights. At the press of the camera’s shutter release, your settings from the master unit are transmitted to the remote Speedlights.
With the digital advantage of immediately viewing the picture, you’ll see the results of your decisions right away. If an adjustment is needed, there's no walking from Speedlight to Speedlight; just change the setting on any group right from the master control unit.
