How does color bit depth affect my image quality?
Think of a box of crayons, the more colors you have, the easier it is to produce subtle variations. 12-bit captures 4,096 shades per channel, 14-bit captures 16,383 shades per channel, and 16-bit captures 65,532 shades per channel. Currently all 35mm format DSLR’s capture in 12-bit, while the majority of digital backs capture in 16-bit. This high dynamic range of a digital back gives you greater color accuracy and depth as well as greater control over your image contrast and exposure.
