Look for a good range of contrast across the brightest and darkest parts of your image and also across the color and tonal range as each color also contains its own brightness or luminance information. “The first step in HDR is to recognize you have a HDR scene. I like the simple approach Atomos takes on this matter: Now the real important question: Do I need HLG?Īs always, it depends.

In theory, with HLG one can shoot, edit, and grade, and the final videos will look good both on normal monitors and on fancy monitors. The second problem HLG is trying to solve is the need to produce two version (HDR and non-HDR) of the same content.

Interesting findings from my recent quest to understand the HLG standard One of the most interesting aspects of HLG is that it is essentially HDR, but compatible with existing standard displays, reducing complexity and cost for both equipment manufacturers and content distributors. HLG stands for Hybrid Log Gamma, which according to Wikipedia is “a backwards-compatible high dynamic range (HDR) standard that was jointly developed by the BBC and NHK.” This is exactly why I waited so long to play with HLG.
