DX-format, 14.2 effective megapixel CMOS image sensor [NEW]
- Softly defocused backgrounds that only a D-SLR can produce

Nikon equipped D3100 with a newly developed CMOS sensor for outstanding subject detail and smooth color gradation. Whether shooting photos or full HD movies, the sensor is crucial to image quality. The high pixel count of D3100's sensor produces photos of striking clarity, revealing all the nuance of the original scene with minimum noise - ideal for intricately detailed textures and grain-free background defocus.

EXPEED 2-Nikon's new image processing engine [NEW]
- Faithful color reproduction and smooth, beautiful gradations

Welcome to a new level of excellence with EXPEED 2. We've leveraged our vast technological know-how to bring you Nikon's most advanced image processing engine yet. EXPEED 2 maximizes CMOS sensor performance for clear, lifelike images that exhibit vivid colors, reduced noise and smooth tonal gradations for outstanding photos and movies.

ISO sensitivity 100-3200 (expandable to ISO 12800 equivalent)
- Great performance and less blur in dimly lit settings

A maximum ISO of 3200 (standard range) lets you shoot at fast shutter speeds, reducing camera-shake blur in dimly lit scenes. Twilight and indoor shots come alive with a refreshingly natural look without the need for a tripod or flash. Moreover, fast shutter speeds make it easy to freeze action in dynamic situations such as children at play and sports events. For added versatility, D3100's Hi 1 and Hi 2 settings effectively boost ISO to the equivalent of 6400 and 12800, respectively.

Active D-Lighting - Beautiful balancing of light and shade

Shooting in bright sunlight often produces pictures with extreme contrast between light and dark areas, resulting in loss of tone and detail. Active D-Lighting effectively combats this by preserving important details in shadows and highlights. The results are optimally exposed photos that better reflect the scene as you saw it.

Picture Control - Customizing images before the shot

Expand creative expression with Picture Control. Six settings - Standard, Neutral, Vivid, Monochrome, Portrait and Landscape - let you determine the look of photos and full HD movies before you shoot. In addition, sharpness, contrast, brightness and saturation can be adjusted to customize settings.
