Bit depth
Techniques Glossary Bit depth
The number of bits used to represent each pixel in a digital image. This figure suggests the image colour or tone range.

Bit Depth:
This refers to the color or gray scale of an individual pixel. A pixel with 8 bits per color gives a 24 bit image. (8 Bits X 3 colors is 24 bits.) Camera sensors are colored in a pixel by pixel method to create an image..

Bit Depth - Number of bits for each pixel in an image. The higher the bit depth, the greater number of colors there are. This is also sometimes referred to as color depth.

Bit Depth
The color or gray scale of an individual pixel. A pixel with 8 bits per color gives a 24 bit image. (8 Bits x 3 colors is 24 bits.) 24 bit color resolution is 16.7 million colors.

bit depth
The size of a value used to represent a pixel in bitmap graphics data. This is usually stated as the number of bits making up the individual data value, or sometimes the number of bytes.

Bit Depth - The number of bits used to represent colors or tones.
Bitmap - An image represented as pixels in a row and column format. (Note that Adobe refers to a bitmap as a two-color image.

Bit Depth
The amount of colour information associated with a digital image. An image with a higher bit depth can display more gradations of colours.

Bit depth
also called pixel depth or color depth--measures how much color information is available to display or print each pixel in an image.

bit depth
The bit depth of an image (also known as colour depth) refers to the number of bits used to describe the colour of each pixel - see colour depth for more on this.

Bit Depth
Defines how many bits of tonal or color data is associated with each pixel or channel. For example, 2 bits per pixel only allows for black or white. 8 bits provides 256 grayscale tones or colors.

Bit depth
Colour depth.
Bitmap
A representational form for a digital image in which each bit in the computers memory corresponds to one dot on the screen or printer.

bit depth
maximum number of bits that are used to define a pixel that is a measure of the defined brightness range.
bitmap
a rasterized graphic image formed by a rectangular grid of pixels or dots.

Bit depth of cameras
TXS for the link to DPReview.
For Nikon cameras, starting with the D300, DPReview states a A/D conversion of 14; therefore I assume that from the D300 upwards the Nikons use a 14 bit sensor.

Colour bit depth: The number of bits used to represent each pixel in an image, the higher the bit depth, the more colours appear in an image. 1 bit colour: black and white image with no greys or colour.

Bit Depth
The color or gray scale of a single pixel. A 24-bit image is created with a pixel that has 8 bits per the three primary colors. (8 Bits x 3 colors is 24 bits.)
Bit ...

Bit depth also plays a role in color space selection. The bits of a digital file must be spread across the entire color space that is used with an image.

Bit Depth
Bitmap
The method of mapping the pixels that make up an image.

Bit Depth - The number or level of grades of color that can be produced by a photo scanner.

Blowup - See "Enlargement." ...

Color or Bit Depth
Just as cameras capture JPEG and RAW images using a different number of bits per color ( 8 or 16) so do scanners. At the moment, most affordable units capture 14 or 16 bits per color—42 or 48 bits total.
Resolution ...

Resolution and Bit Depth
True scanner resolution is optical resolution, not interpolated resolution. Interpolated resolution will read higher than optical because it's been enhanced by the software bundled with the scanner.

There is also a "bit depth" to digital image files. Each pixel recorded during the scan has color information assigned to it. Each pixel's color information is saved as a number of bits (8 bits = one byte) for each color channel (red, green, blue).

Here, you can select the bit depth, size and resolution you want along with the target color space. ACR gives you the option to keep the image the size it was shot or to upsize or downsize it during the conversion process.

Bit depth refers to the number of points of data between values or the fineness of the increments in the scale.

When it comes to the camera, I understand, any camera that may have the mechanism to deliver more bit depth is the better.

While the whole theory of bit depth is beyond my space allotment (not to mention my knowledge), the RAW protocol box offers the option of opening an image in 16-bit or 8-bit. Always open in 16-bit.

Converter EX allows you to select your output bit depth and color space at the time you drop an image or group of images onto the application. Note that you can only select Adobe RGB with a 16-bit TIFF output (each one 71,103 KB).

A 16-bit depth is usually divided into five bits for each of red and blue, and six bits for green (most human eyes are more sensitive to green than the other two primary colors). A 24-bit depth allows 8 bits per component.

PSD - here you can set the bit depth. Usually the 16-bit is better especially if you intend to work on the file in other software, because that way the maximum amount of data from the raw capture will be preserved in the rendered file.

Bit Depth A measurement of the number of bits used to create a single pixel in a digital image. A 24-bit RG8 image is created from a palette of 16.7 million colors.

The ratio of the saturation to noise, limited by the bit depth of the sensor. Dynamic range is expressed numerically (3.0 for example). In the captured image the dynamic range relates to the colour fidelity and contrast range of the picture.

A Drum Scanner with a Dynamic Range of 3.8D and a bit depth of 48 will produce a much higher quality, richer, more detailed scan than a Flatbed Scan with a Dynamic Range of 2.5D and a bit depth of 24 at the same scan resolution.

In future tutorials we will discuss more advanced concepts within Adobe Camera Raw such as determining the best bit depth and color space for your Raw output files, as well as items like Lens Corrections and Camera Calibration.

GIF = Graphic Interchange Format, 8-bit file format (or lesser bit depths, that is, 256 or less colors) developed specifically for the Internet by Compuserve.

Color depth is sometimes referred to as bit depth because it is directly related to the number of bits used for each pixel. A 24-bit video adapter, for example, has a color depth of 2 to the 24th power (about 16.7 million) colors.

True Color - A 24-bit color depth. See bit depth for more information.
TWAIN - A standardized interface that allows software to communicate with scanners and digital cameras.

Colour Depth - Digital images can approximate colour realism, but how they do so is referred to as colour depth, pixel-depth, or bit depth. Modern computer displays use 24-bit True Colour.

Dot
The smallest raster element of an image. Many dots together produce one pixel. Meaning, for example, that in the specification "8 bit depth", three "layers" of 256 dots each are on top of one another to produce one pixel.

If your scanner doesn't capture the subtle differentiations between grays (in black-and-white scans) and between colors (in color scans), then this information from the original is lost. This differentiation ability is called color depth or bit depth.

but the basic principles apply to most other scanner technologies. You will learn about the different types of scanners, how the scanning mechanism works and what TWAIN means. You will also learn about resolution, interpolation and bit depth.

In conventional photography this is measured in stops (a stop equals a factor of 2 in brightness, e.g. 5 stops = 32 times brightness difference, 10 stops = 1024 times). For digital cameras it is normally represented by the bit depth, usually 24bits.

The higher the bit rate of this conversion, the higher the image quality. Nikon D-SLRs typically offer a 16 bit image processing pipeline, which converts images of 12 bit or 14 bit depth quickly and efficiently.
