NEW SENSORS
New sensors and programming are at the heart of
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.
New Nikon DX Format JFET Image Sensor
LBCAST
In developing the image sensor for the
LBCAST
speed and power efficiency. 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 significantly reduces power consumption over previous generations, minimizes dark noise, and realizes these features while increasing speed. It combines JFET (Junction
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
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 specific assignment and workflow environment.
Mode I : sets hue and chroma values that are effective in rendering
8
Mode II : realizes a wider color reproduction range for
output with a wider color gamut. (Color profile: Adobe RGB)
Mode III : sets hue and chroma values for landscape and flora
colors. (Color profile: 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 difficult when the subject is, for example, set against a backdrop of a single color. With one sensor for reading reflected light, a second for reading the image area during exposure, and a third for incident reading,
the three-sensor system adds
The three sensors make it possible to shooting with | Ambient light sensor |
greater white balance accuracy, even under conditions |
|
that complicate white balance adjustment, such as |

when the subject displays little variation in tone. |

unprecedented depth and flexibility in measuring and comparing color temperature to achieve optimum white balance.

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 refined 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 five 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 find 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
New JPEG and RAW (NEF)
Combination Filing System
Another Nikon first 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 workflow operations by selecting the file 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 files from the same shot. Use JPEG for faster image transfer and keep the NEF as your ultimate electronic image file. NEF format is always a convenient option as you can later make
