Creative Lighting System
Creative Lighting System is an interface from the Japanese manufacturer Nikon , which is used for communication between cameras and flash units. It was introduced in 2003 with the Nikon D2H .
Functions
The i-TTL (intelligent Through-The-Lens) as the successor to D-TTL (digital TTL)
With D-TTL, a pre-flash was triggered after the mirror was folded up and - in contrast to TTL with analog cameras - before the shutter was opened. The light reflected by the neutral gray shutter was then measured. Since only an integral measurement is possible here, the D-TTL method was only suitable to a limited extent for the balanced coordination of flash and ambient light. D-TTL was only used by Nikon in the first series of digital SLR cameras (D1 series and D100, the D2 family already supports i-TTL, but is still downwards compatible). D-TTL technology has been integrated into the SB-28DX, SB-50DX and SB-80DX flash units; the SB-600 and SB-800 are the only Nikon flash units capable of both D-TTL and i-TTL.
In contrast to D-TTL, the further development i-TTL uses a pre-flash measurement with the regular exposure measurement sensor built into the pentaprism viewfinder. The measuring flashes are fired when the mirror is not yet raised. On the part of the camera, a comprehensive multi-field evaluation is possible for the first time, in which a subject-dependent analysis of the brightness of individual image areas can be carried out with and without a measuring flash. The number of measuring flashes required depends on the subject. As a characteristic of this process, the photographer sees i-TTL (in contrast to D-TTL, TTL from analog times and classic / manual non-TTL flash) for the first time in the viewfinder of a SLR camera "his" own flash - even if it is only there is the usually weaker pre-flash.
The FV flash measured value memory
was integrated into the SB-800 with the CLS system. It enables the flash intensity determined by the iTTL to be saved and applied to several recordings and series recordings. If the exposure control changes, this value is automatically adjusted.
The automatic FP short-term synchronization
allows you to shoot with flash for very short exposure times below the sync time of a compatible camera. This function is z. B. used to brighten up dark parts of the picture in otherwise very bright surroundings, or in order to be able to use a wider aperture than normal flash exposure would allow in a bright environment to control the depth of field .
The transmission of the color temperature information
is used to adjust the white balance of the camera used to the changing color temperature of the flash. The information about flash intensity and burn time is automatically passed on to the camera. In this way, the camera can adjust the white balance to the changes in the color temperature of the flash.
The wide-angle AF-assist illuminator
is an infrared grid that is emitted by the flash unit in the direction of the camera when the ambient light is weak in order to give the autofocus module sufficient contrast. It has been adapted to the DX format in order to fully illuminate the wide-angle area and to enable focusing on objects in the edge of the image.
The Advanced Wireless Lighting
describes the wireless remote control of unleashed flash units . The SB-800 either acts as a control unit to fire other flash units wirelessly using control flashes, or as a receiver unit to receive from another control unit (e.g. another SB-800, SU-800 or the integrated flash unit of a camera , which also has the control function) to be remotely ignited. The receiver flash units can be divided into up to three groups. Each group can be given different exposure values. In order to differentiate between several camera flash sets set up in this way, two different channels can also be used. This is to prevent the mixing of the control signals, which otherwise cannot be separated as optical signals (control flashes).
