    What is bit depth?

    What is bit depth?

    Bit depth refers to the number of bits of data used to record each pixel in the image. The greater the bit-depth, the greater the range of tones and colors recorded, and the smoother the tonal transitions in your image.

    Most images are 8-bit, or may be referred to as 24-bit. (There are three color channels in each image – red, green and blue – each containing 8-bit data, hence ‘24-bit’).

    Normally, this is plenty, and images don’t show any obvious steps in tone or color.

    However, after heavy manipulation, blotchiness, banding or posterisation effects can occur.

    It is possible to save images in 16-bit mode, which produces far smoother tones, but for this you need a camera which can shoot raw images and a program that can edit them (like Photoshop).
