The Nikon Creative Lighting System (CLS) Nikon's advanced Creative Lighting System (CLS) offers improved communication between the camera and compatible flash units for improved flash photography. The Creative Lighting System supports the following features: • i-TTL flash control: Improved through-the-lens (TTL) flash control for use with CLS (see page 193). Flash level is set using monitor pre-flashes to measure the light reflected by the subject, ensuring that the level is adjusted appropriately for ambient lighting. • Advanced Wireless Lighting: Allows i-TTL flash control with remote wireless flash units. • FV lock (pg. 198): Locks flash level at the metered value, allowing a series of photographs to be taken at the same flash level. • Auto FP High-Speed Sync (pg. 197): Allows the flash to be used at the highest shutter speed supported by the camera, making it possible to choose the maximum aperture for reduced depth of l field. The CLS-compatible D3X can be used for flash photography when an optional Speedlight is mounted on the camera's accessory shoe. A flash can be used not only when natural lighting is inadequate, but also to fill in shadows, illuminate back-lit subjects, and even to add a catch light to the eyes of a portrait subject. See the Speedlight manual for details. 186
