Dynamic range also known as to

(1) The range between the lightest and darkest areas of an image. A picture containing very bright areas and very dark areas has a wide dynamic range. In a black and white image, dynamic range refers to the various shades of gray between solid black and absolute white. (2) The measure of the range of brightness levels that can be recorded by a camera s sensor. (See Clipping for further info on overexposed areas of an image.).

Dynamic area af

Dynamic Area AF is one of three Nikon AF Area Modes. With Dynamic Area AF, you can select from several focusing options: 9-, 21- or all 51-point AF. Select a Single AF point and the areas surrounding it serve as backup—a significant advantage when shooting moving subjects. Select the 9-point option when you want to focus on erratically moving subjects with greater accuracy. When dealing with insufficient contrast for fast focus detection, choosing 21 or 51 points makes detection easier. The 51-point option also allows for 3D Focus Tracking, which uses color information from the RGB metering sensor to automatically follow moving subjects across the AF points.

Dynamic range

This is a measurement of the accuracy of an image in colour or grey level. More bits of dynamic range results in much finer gradations being preserved.

Dynamic range

Expressed as a ratio, the measurement of the range of brightness (contrast) in a scene. Typically, it is 40:1, with 100:1 a maximum. Camera with wide dynamic range able to operate in variable light conditions, especially low light. Measurement of highest and lowest levels device can attain, with video, measurement of contrast, with audio device, usually stated in dB.

Dynamic range

The range of brightness and tonality reproduced in a digital (or traditional) photographic image. Wider dynamic range translates into greater tonal values (and detail) between the darkest shadows and the brightest highlights.

Dynamic range

Often quoted on scanner specifications to indicate the maximum tone range that the scanner can capture. A higher figure indicates that the scanner will capture more detail from the highlights to shadows. With flatbed scanners that are being used to scan prints this isn t too important because the tonal range has already been reduced in the printing process. A higher dynamic range is essential on film scanners when scanning transparencies that have a wide tonal range. Specialist films, such as Fuji Velvia, are said to have a range of around 3.7D, so the scanner needs to have at least the same dynamic range to ensure every bit of highlight and shadow detail is captured in one scan.
