Though Face Detection is helpful in Live view mode, its utility goes further, as it's now an integral part of Nikon's Scene Recognition System (SRS). Thanks to the Nikon D90's 420-pixel matrix metering sensor, the SRS can combine color metering with autofocus sensor data and tune white balance and exposure with a particular bias toward getting faces exposed properly. In theory, this should also include making sure the Nikon D90 focuses on an eye rather than a nose or forehead. If true in practice, this is quite an advance. Face detection even comes into play in i-TTL Flash control. Automatic correction of lateral chromatic aberration for JPEGs. Correction-data is additionally stored in RAW-files and used by Nikon Capture NX, View NX and some other RAW tools. Programmable function button is very handy, position under right middle finger is convenient, makes it easy to manipulate main command dial at the same time The Nikon D90 allows for images to be captured in one of six Picture Styles, ranging from Standard and Neutral to the new Portrait and Landscape modes, or alternatively in a customised style of your choosing. In either case, the D90’s Scene Recognition system optimises exposure, white balance and focus, and also works in tandem with face recognition technology. All of this is aided by the camera’s 420pixel RGB metering sensor, which offers a standard evaluative matrix pattern in addition to centre-weighted and spot options. Just so you know keeping the image sensor clean is crucial. However, it’s quite a hassle and really risky to the sensor if you don’t know what to do. With the Nikon d90, you have 4 effective ultrasonic sensors which help you keep the camera sensor clean. Auto Focusing System
The Nikon D90’s sensitivity ranges from ISO 200-3200, and may be extended a stop each way to ISO 100 and 6400. Working with this is Nikon’s Active D-Lighting function, which essentially optimises dynamic range for enhancing otherwise-lost detail. This may be either left to an auto setting or configured manually, and – for the first time in the Nikon D90– the function sees an ‘Extra High’ option, for those oc The Nikon D90 is Nikon's newest and smartest DSLR. It has the same or better technical image quality as the D300 that costs much more, and it handles better and it makes movies, too!The D90 has a larger screen size of 3 inches, compared to the D80’s 2.5 inches. This allows for better image preview and camera setting adjustments. Furthermore, the D90’s screen resolution is significantly higher at 920,000 dots, compared to the D80’s 230,000 dots. This results in a sharper and clearer display, enhancing the user’s experience. Barnett, Shawn; Etchells, Dave; Weidelich, Zig (October 20, 2008). "Nikon D90 Video". The Imaging Resource .

The heart of the D90 is the 12.3 megapixel CMOS sensor in the DX format, which is the brand name that Nikon has given the cropped sensor format. As with all cropped sensor cameras, the D90 uses a smaller sensor, which costs less to manufacture and is the key to cameras at this price point. In the case of the D90, the sensor measures 23.6mm x 15.8mm. While cheaper to manufacture, these smaller sensors are very capable of capturing outstanding images in a wide variety of lighting situations. Shows shutter setting, but ignores it. (Live view has the same idle screen, not knowing if you're about the shoot a movie or a still) When choosing a lens for the Nikon d90, you should prioritize focal length, aperture, and your photography purpose. If you keep these three things in mind it’ll be easier for you to find the right lens. Key Features Of Nikon D90 Nikon finally fixed the design flaw where by default the Modeling Flash fired if you hit the Depth-of-Field preview button. Thank you Nikon! Still a crappy, small finder compared to any film or FX camera: remember, the 96% coverage is of a frame only 0.65x the size of FX.In terms of image quality the results were generally very good. The level of overall detail is very close to matching the performance of the D300, although that camera’s 14bit A/D conversion gives it the edge in colour depth, contrast and general sharpness. I also found that the exposure meter produced slightly varied results in low light, with repeated exposures under similar lighting conditions varying by around half a stop either way. The Self Timer can make multiple exposures, helping ensure everyone's eyes are open in at least one of the shots. The d90 model comes with 3 inches with 170 degrees wide angle LED display. It allows you to capture your photographs by viewing more details and also helps with capturing video footage. Integrated Inbuilt Buttons The Nikon D90 is the world’s first DSLR to introduce 720p high definition video to the market, whilst successfully upgrading the popular mid-range Nikon D80 model. And yet already, with the D90 barely on the shelves, internet forums have been steadily filling up with arguments from both sides of the ‘video/photo’ fence. Some argue the Nikon D90’s dive into HD video makes both economical and practical sense, allowing effortless transition between the use of both mediums. Predictably, the opposing argument has been just as vocal, with people stating that they don’t need DSLR video capture. Like it or not, it looks like DSLR video is here to stay – but as the Nikon D90 is the first model of its kind, exactly how high should we be setting our expectations?
