8-bit, 16-bit, 32-bit… What does bit depth mean, and what is a good bit depth to use?
In this class, Karl answers these questions as he explains what bit depth is and why it’s an important concept to understand in photography.
Quite simply, bit depth (also known as colour depth) refers to how much colour, brightness, and saturation can be displayed in a single pixel. Karl explains this in further detail throughout this class as he shows the visual differences between an 8-bit image and a 16-bit image. He also discusses the advantages and disadvantages of larger bit depths and why it’s still important to choose the right one and explains what bit depth is used for printing and why a higher bit depth is the best option for retouching.
