Optional Flash Units (Speedlights) The D300 can be used with CLS-compatible flash units. 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 172). 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. 180): 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. 289): 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 field. n 357
