Nikon 1799 instruction manual Advanced Wireless Lighting, Modeling flash, FV Lock, 151

•Advanced Wireless Lighting

Multiple SB-800/SB-600 flash units can be used to eliminate shadows for a natural lighting effect or to light other areas of the frame, away from the main subject.

Supported flash modes include i-TTL flash control, AA (Auto Aperture) and manual operation. A master Speedlight, mounted on the camera or connected using an SC-29 TTL Remote Cord, can control up to three groups (A, B, C) of remotely positioned Speedlights using wireless operation. The master Speedlight must be a Nikon SB-800, while remote units can include SB-800/SB-600. Using multiple Speedlights enables creative lighting; it is possible to turn off the illumination from the master Speedlight and enable it to control all of the remote units, or you can allow the main Speedlight to add to the lighting arrangement. See Speedlight instruction manual for details.

Modeling flash

SB-800/SB-600 Speedlights emit a modeling flash when the camera depth-of- field preview button is pressed. This feature can be used with Advanced Wireless Lighting to preview the total lighting effect achieved with multiple flash units. Modeling flash can be turned off using Custom Setting “e4: Modeling flash” (x 105).

•FV Lock

This feature is used to lock flash output, allowing photographs to be recomposed without changing the flash level.

This ensures that flash output is appropriate to the subject even when the subject is not positioned in the center of the frame. Flash output is adjusted automatically for any changes in sensitivity (ISO equivalency), aperture, and Speedlight zoom head position. FV Lock is available with i-TTL and Auto Aperture flash control, Advanced Wireless Lighting, and Auto FP High-Speed Sync. For using FV Lock, see the next page.
