Auto white balance that supports various light sources accurately
The D610 detects color and brightness information of the shooting scene before shooting utilizing the Scene Recognition System and identifies the light source highly accurately by referencing its massive collection of in-camera shooting data. The auto white balance accuracy for common shooting scenarios has been enhanced, enabling the camera to reproduce colors naturally and precisely both indoors and outdoors. In addition to the conventional setting of Auto 1 (Normal) that compensates lighting colors, the D610 allows you to set another auto white balance mode, Auto 2 (Keep warm lighting colors), that maintains warm lighting ambience when you shoot under incandescent light. If the image is shot in RAW, these modes can be applied using the NEF (RAW) processing of the D610's in-camera retouch menus regardless of the shooting setting.
Wide standard ISO sensitivity ranging from ISO 100 to 6400, that handles various degrees of brightness
The D610's standard ISO sensitivity, that clears Nikon's severe test conditions, ranges from ISO 100 to 6400. Under harsh lighting conditions, it is possible to expand to ISO 50 (Lo 1) or ISO 25600 (Hi 2) equivalent. The D610's large FX-format CMOS sensor responds to a variety of lighting situations such as the harsh glare of the midday sun, the low light of dusk, a dimly lit interior and night scenes. Also, the superior noise reduction function reduces noise effectively at high ISO setting, and suppresses noise even for low-contrast subjects such as hair and grass textures while maintaining resolution as much as possible. This excellent high ISO sensitivity performance is powerfully effective even in movie recording.
Nikon's noise-reduction method
Thanks to its improved image-processing performance and a comprehensive noise reduction system, the D610 successfully minimizes noise at higher ISOs while substantially broadening the standard ISO range. What makes Nikon's noise-reduction method superior is that noise appearing in an image is analyzed, and then optimized noise reduction is applied accordingly. The result: effective noise control in your movies and still images, all without sacrificing the fine details.
Auto ISO sensitivity control* that changes sensitivity automatically
Auto ISO sensitivity control lets the camera adjust ISO sensitivity automatically if optimal exposure cannot be achieved at the selected value. The D610 comes equipped with an "Auto" option for minimum shutter speed. The shutter speed at which the camera will start increasing ISO sensitivity for optimal exposure is automatically selected based on the lens focal length. This enables shooting with efficiently reduced camera shake when using a zoom lens or if the lens is changed. The controlled value can be minutely adjusted according to the subject's movement or photographer's needs. Auto ISO sensitivity control can be set using the menu, and can also be immediately accessed with the ISO button and sub-command dial.

Active D-Lighting with enhanced image quality
Active D-Lighting preserves details in both highlights and shadowy areas, maintaining moderate contrast to reproduce brightness as you see it, even when shooting high-contrast subjects in backlit situations. The D610 employs a new image-processing system that delivers superior reproduction without shifting color phase even when the strength level is increased. It reproduces brightness as you see it even in high-contrast lighting scenes such as gradation of the sky. Image-processing time is shortened by high-speed and highly accurate, real-time processing within pipelines. And color reproduction is improved thanks to the EXPEED 3 image-processing engine. Active D-Lighting is suitable for moving subjects such as people while HDR is effective for stationary subjects.
HDR (High Dynamic Range) that produces a single image with a wider dynamic range
Two images taken with one shutter release at different exposures are combined to produce a single image that has a wider dynamic range. Since exposure differential can be expanded up to 3 EV, the result is images with less noise and rich tonal gradation including shadows and highlights, even for high-contrast shooting scenes. The smoothness of the edge where the two exposures meet can be adjusted (the degree is selectable from high, normal and low) according to your intention. HDR is ideal for stationary subjects such as high-contrast landscapes and still lifes.
Note: Tripod use is recommended.
Lateral chromatic aberration reduction/auto distortion control/vignette control that support sharp resolution even in peripheral areas
Unlike other correction methods that simply eliminate the colors of chromatic aberration, Nikon's lateral chromatic aberration reduction compensates for the differences in the resolving sizes of each color. This proves especially effective for reducing image distortion at the edges of a frame and for improving image quality throughout the entire frame, regardless of the NIKKOR lenses used. If you set "On" for "Auto distortion control" when using G or D lenses*1, barrel distortion caused by a wide-angle lens or pin-cushion distortion caused by a telephoto lens can be compensated. Also, it employs "Vignette control*2" that reduces the drop in brightness at the edges of a photograph caused by characteristics of the lens.
