Nikon D3x Mode D'Emploi

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 
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.
