You can see or convert bit depth by choosing Image ➪ Mode ➪ Bits/Channel. At a basic level, all digital images contain components called pixels. Pixels can contain varying amounts of information that describe their color. In this case, color refers to the qualities of hue combined with lightness.The greater an image’s bit depth, the more information each of its pixels can contain, and the more colors each of those pixels can potentially be. Therefore, the higher an image’s bit depth, the more colors and degrees of brightness the image can contain (see Table 1.1).
