Speedlight for nikon

Nikon has today announced the new SB-800 Speedlight. This new flash unit is designed to complement the D2H digital SLR and incorporates many new features associated with Nikon's i-TTL 'Creative Lighting System' including Flash Value Lock, Auto FP High-Speed Sync and Flash Colour Information Communication. The SB-800 also facilitates advanced wireless lighting, "Up to 3 SB-800 units can now communicate monitor pre-flash data with the Master unit for fully automatic multiple flash exposures, removing the need for flash meters or manual calculations. The D2H Digital SLR 1005-pixel Matrix metering sensor is utilized to calculate exposures, and transmit each Slave output changes back to each Slave unit."

At the heart of a new Nikon Creative Lighting System

Introducing the Nikon Speedlight SB-800, an intelligent, flexible breakthrough in flash photography that forms the heart of a new Creative Lighting System. Refined digital performance and new technologies to make complex multiple flash exposures as simple as using a single on camera flash unit.

Intelligent, innovative, indispensable

The new Speedlight SB-800 introduces a number of refinements to D-TTL flash performance technologies, Nikon term i-TTL.

Flash Colour Information Communication

A new system designed to improve AWB (Auto White Balance) irrespective of flash output duration. Until now flash lighting can exhibit changes to AWB depending on flash to subject distances. Long (distant) duration outputs tend to be redder, short (close) durations tend to the bluer end of the spectrum.

The new SB-800 incorporates systems that communicate flash output information during exposures to the image processing ‘engine’ of the new Nikon D2H Digital SLR.

The principle is to deliver uniform AWB results during flash exposures of varying subject distances.
