Practical High Dynamic Range (HDR) Broadcast Workflows - Part 2May 4th 2021 - 09:00 AM

There is a school of thought that suggests increasing the brightness through the contrast control on a television will give a higher dynamic range. However, this doesn’t necessarily increase the contrast ratio. Quantization noise is the enemy of dynamic range and increasing brightness in a system with a low bit depth makes quantizing banding obvious. When banding occurs, the brightness must be turned down to remove it or, the bit depth should be increased.
