Practical High Dynamic Range (HDR) Broadcast Workflows - Part 2 May 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.

Practical High Dynamic Range (HDR) Broadcast Workflows - Part 1 April 27th 2021 - 09:30 AM

HDR is taking the broadcasting world by storm. The combination of a greater dynamic range and wider color gamut is delivering images that truly bring the immersive experience to home viewers. Vibrant colors and detailed specular highlights build a kind of realism into broadcast productions that our predecessors could only ever have dreamed of.
