What is Color Depth?

The number of distinct colors that can be represented by a piece of hardware or software. 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 digital camera, for example, has a color depth of 2 (2 bits of color) to the 24th power, resulting in a dynamic range of 16,777,216 colors. Similarly, an inexpensive 8-bit color monitor can only reproduce a total of 256 colors, which is far less than the expansive range of color contained in the digital image files captured by almost all consumer digital cameras.
