Active D-Lighting
When Active D-Lighting is on, the capacity of the memory buffer drops 
and additional time is required to record images (pg. 429). Matrix 
metering is recommended (pg. 110). Although exposure is in fact reduced 
to prevent loss of detail in highlights and shadows, highlights, 
underexposed areas, and mid-tones are automatically adjusted to prevent 
the resulting photograph from being underexposed. The [Brightness] and 
[Contrast] Picture Control settings (pg. 167) can not be adjusted while 
Active D-Lighting is in effect.
 Noise, distortion, or banding may be visible 
at high ISO sensitivities. In exposure mode h, an Active D-Lighting setting 
of [Auto] is equivalent to [Normal].

“Active D-Lighting” versus “D-Lighting”
The [Active D-Lighting] option in the shooting menu adjusts exposure 
before shooting to optimize the dynamic range, while the [D-Lighting] 
option in the retouch menu optimizes dynamic range in images after 
shooting.
