unprecedented depth and exibility in

measuring and comparing color temperature

to achieve optimum white balance.

1) Nikon's acclaimed 1,005-pixel RGB

Exposure / Color Matrix Metering Sensor

performs direct TTL metering of the subject.

2) The LBCAST image sensor calculates

the lighting characteristics of the image data

in real time.

3) The new external Ambient Light Sensor

meters ambient light without being affected

by the color of the subject.

The system also features revised integrated

signal processing and AWB and ATC

algorithms that contribute to rened color

and tone reproduction.

New Manual White Balance &

White Balance Bracketing

New to the selection of eight manual white

balance modes is the Color Temperature mode that responds

to the needs of the photographer by adding the ability to select

Kelvin color temperature settings directly from 31 values covering

a range between 2,500 K and 10,000 K.

Preset mode allows quick selection from ve white balance

settings stored in memory to match a frequented venue or

other conditions you shoot under regularly. The settings can be

derived from a standard gray card reading, extracted from the

CompactFlash memory card using the setting from an image

taken by the camera, or from values created in Nikon Capture 4.

White balance bracketing makes it easy to test different settings

and nd the one that best suits the assignment. Bracketing for 2

to 9 consecutive frames is available in adjustable increments of

10, 20 or 30 MIREDs.

Real-time Noise Reduction

The results of this new automated process rival the quality

of using the noise reduction setting available on the previous

generation. However, the new signal-processing engine delivers

this performance instantly and with no need to run a second pass

to make the necessary correction. The D2H also continues to

offer yet a higher level of noise reduction via the selectable noise

reduction function.

New JPEG and RAW (NEF)

Combination Filing System

Another Nikon rst for the D2H is the option

to simultaneously record RAW (NEF: Nikon

Electronic image File) and JPEG data for

the same shot to the camera's storage

media. Now you can optimize and speed

up workow operations by selecting the le

type or types that best suit your shooting

conditions.

Choose to shoot using only NEF or only

JPEG format, or have the D2H produce

both les from the same shot. Use JPEG

for faster image transfer and keep the NEF

as your ultimate electronic image le. NEF

format is always a convenient option as you

can later make non-destructive edit changes

to your NEF le and subsequently produce

JPEGs and TIFFs from the NEF le.

natural-looking skin tones in portraits. (Color prole: sRGB)

Mode II : realizes a wider color reproduction range for high-quality

output with a wider color gamut. (Color prole: Adobe RGB)

Mode III : sets hue and chroma values for landscape and ora

colors. (Color prole: sRGB)

Precise Auto White Balance / Auto Tone Control

The new advanced Auto White Balance (AWB) and Auto Tone

Control (ATC) system developed for the D2H combines the

advantages of three separate sensors to effectively handle

complicated lighting conditions. AWB searches for white to use

as reference and distinguishing color can be difcult when the

subject is, for example, set against a backdrop of a single color.

With one sensor for reading reected light, a second for reading

the image area during exposure, and a third for incident reading,

the three-sensor system adds

New Nikon DX Format JFET Image Sensor

LBCAST

In developing the image

sensor for the next-generation

D2H, Nikon aimed to mate the

best aspects of performance

to achieve the optimal

combination of image quality,

speed and power efciency. The result is the new JFET image

sensor LBCAST, an exclusive Nikon design that combines

performance innovations with the successful DX Format.

The LBCAST sensor signicantly reduces power consumption

over previous generations, minimizes dark noise, and realizes

these features while increasing speed. It combines JFET (Junction

Field-Effect Transistor) technology and LBCAST (Lateral Buried

Charge Accumulator and Sensing Transistor array) architecture

with a host of innovations to render color, detail and sharpness as

never before. Compare an image from this new sensor and you

soon realize that speed, precision, accuracy, color and detail are

the hallmarks of the LBCAST sensor and the D2H.

The sensor’s Optical Low Pass Filter (OLPF) effectively

suppresses moiré patterns while its thinner new design also

assures that it does not reduce image sharpness.

The new image processing engine

The new highly advanced image-processing engine on the system

LSI features improved algorithms for 3D Matrix Image Control and

innovative technologies that deliver subtle color gradations and

smooth diagonal lines while diminishing color fringing and false

colors. A wide range of aspects related to image quality affect

sharpness, and the new LBCAST sensor uses advanced imaging

technology to address them all – including control over noise,

color artifacts, jaggies and false colors. The result is a superior

combination of high speed and faithful color reproduction with

sharper details.

Three color modes

The color reproduction system newly developed for the D2H

improves on Nikon's already unrivalled color while optimizing the

three available color modes to best match the specic assignment

and workow environment.

Mode I : sets hue and chroma values that are effective in rendering

The three sensors make it possible to shooting with

greater white balance accuracy, even under conditions

that complicate white balance adjustment, such as

when the subject displays little variation in tone.

Ambient light sensor

New sensors and programming are at the heart of

next-generation D2H performance

Total Image Quality requires each component to perform optimally.

The sensors and processing algorithms newly developed for the D2H demonstrate Nikon's determination to

deliver perfectly combined technologies that respond to the photographer's needs.
