Nikon’s revolutionary Advanced Scene
Recognition System, introduced with the
flagship D4 camera, is also employed in the
D800. At its core is a 91K-pixel RGB sensor
that meticulously analyzes each scene
with the fine resolution. The RGB sensor
can recognize your scene’s colors and
brightness with unprecedented precision,
then use that information to implement various automatic
controls and give you more natural-looking results. The real
breakthrough, however, is that the sensor can detect human
faces with startling accuracy when shooting through the
optical viewfinder. Along with face detection, detailed scene
analysis is utilized to support more accurate autofocus, auto
exposure and i-TTL flash exposure results in a diverse range
of compositional and lighting
situations. The improved subject
tracking is most noticeable
when using 3D-tracking, which
can maintain a focus on moving
subjects smaller in size than
with previous generations.
Auto-area AF and 3D-tracking are AF-area modes unique
to Nikon that use your subject’s color and brightness
information to detect focus. With the D800 and its more
precise information and subject recognition advancements,
expect big steps forward for both AF-area modes when
taking high-quality still images. In auto-area AF, the camera
can genuinely detect human faces and focuses on them
immediately — useful when faces are a priority and there’s
no time to choose focus points. When using 3D-tracking,
the sensor’s fine resolution combines with a specifically
optimized AF algorithm to realize unprecedented subject
tracking precision, recognizing detailed patterns to keep your
subject in sharp focus.
Professional photographers who shoot still images know that
Nikon’s metering system delivers supremely well-balanced
exposures. Thanks to the 91K-pixel RGB sensor, the D800
has far more detailed scene information at its disposal —
including detected face information. This data helps the
3D color matrix metering III deliver more desirable auto
exposures, especially when there are human faces present.
When the D800 recognizes a human face in a backlit
situation, the camera determines the overall exposure while
prioritizing the facial exposure, which might otherwise be
underexposed. When a face is lit from the front and appears
much brighter than the background, the camera recognizes
the situation and avoids blowing out the facial details.
Nikon’s i-TTL system has long been considered the
most accurate flash control system in photography,
but now face detection and highlight analysis by
the 91K-pixel RGB sensor pushes performance
even further. With the D800’s enhanced
i-TTL balanced fill-flash, you can more
precisely illuminate people’s faces in relation
to their surrounding brightness using either the built-in flash
or an external hot-shoed Nikon Speedlight. For weddings
and fashion shoots, or any photography that
relies on the highest-quality still images, this
new standard redefines what a flash system
should be. Face detection also makes a
difference when Active D-Lighting is used to
retain highlights and shadows in high-contrast
lighting situations. Faces will be optimally
exposed both in the sun and in the shade.
The D800’s auto white balance is incredibly accurate in a
diverse range of shooting situations, aided by unique Nikon
technology that effectively identifies your light sources, both
natural and artificial. With the 91K-pixel RGB sensor and the
image sensor working together, the camera renders white
as white with supreme accuracy. Or if you prefer, the auto
white balance can be set to reflect the warmth of ambient,
incandescent lighting.
Accurate AF detection is crucial
for extremely high-resolution still
images in every situation. The
51 sensor points in the D800’s
AF sensor module work down to
-2 EV (ISO 100, 20˚C/68˚F), the
approximate physical limit of human
visibility through an optical viewfinder. For even more
powerful detection, you can rely on the camera’s 15 cross-
type sensors in the center to detect both vertical and
horizontal lines when using any AF NIKKOR lenses of f/5.6
or faster. What’s more, AF can be
activated with eleven focus points
in the center with open aperture
of f/8*, which is a big plus when
you combine a telephoto lens
with a 2.0x teleconverter to shoot
distant subjects.
*Cross-type sensor is limited to the center
AF point only. AF may not be achieved in low-
contrast or low-light conditions.
Whether it’s a still life, a portrait, a landscape or a candid
street scene, your subject matter varies, but its importance
doesn’t. That’s why the D800 offers four AF-area modes,
each specifically tailored to adapt to various subjects. Single-
point AF is ideal when you need pinpoint focus on stationary
subjects. Dynamic-area AF has three options (9-point,
21-point and 51-point) and is ideal for shooting moving
subjects. The selected AF point and the surrounding points
keep your subject in sharp focus even if it briefly leaves the
selected points. 3D-tracking allows you to maintain focus on
subjects that are moving erratically from side to side. Auto-
area AF detects human faces
and prioritizes their sharpness for
you — an ideal choice for candid
photography.
