Chapter 1. Digital Camera Raw > Using All the Bits

Using All the Bits

Most of today's cameras capture at least 12 bits per channel per pixel, for a possible 4,096 levels in each channel. More bits translates directly into editing headroom, but the JPEG format is limited to 8 bits per channel per pixel: So when you shoot JPEG, you trust the camera's built-in conversions to throw away one-third of your data in a way that does justice to the image.

When you shoot raw, though, you have, by definition, captured everything the camera can deliver, so you have considerably more freedom in shaping the overall tone and contrast for the image. You also produce a file that can withstand a great deal more editing in Photoshop than can an 8-bit per channel JPEG.
