HLG takes a different approach. Instead of starting with an HDR signal, HLG begins with a standard dynamic range (SDR) signal that any TV can use. The extra information for HDR rendering is added

Even better, HLG allows the existing production ecosystem for SDR TV to be used for HDR production - it also provides a way to broadcast live HDR. The "hybrid" part of Hybrid Log-Gamma

Dolby Vision: A Proprietary Format with Dynamic Metadata. Dolby Vision is a direct competitor of HDR10+, and it shares many similarities from a technical standpoint. Current Dolby Vision content is mastered at a brightness of up to 4,000 nits, with support up to 10,000 nits, 8K resolution, and 12-bit color in the future.

In the early days of HLG, we only had demos shown at technology shows and press events to illustrate what the format's potential could be. All that changed in December 2017, when the BBC launched the seven-episode Blue Planet II in 4K and HLG HDR on its iPlayer service. It was the first time a full series had been shown in both technologies - no mean feat, and it looked fantastic.

If a TV says it's HDR-ready, it almost certainly supports HDR10 and probably HLG, but Dolby Vision and HDR10+ are more of an either/or situation, at least for now.

First, it is limited to 10-bit color depth while HDR10 can have 12-bit. It has also been lagging behind HDR10 in being integrated into displays. While it usually only takes a firmware update to enable HLG, HDR10 (and the other HDR formats) have already seen wide adoption. Because of the lower bit depth, HLG has smaller files and has really only

Both offer HLG as a setting and mention it as a means for achieving "instant HDR," and it is extremely likely that future cameras will offer the same function because HDR is here to stay. For those of you who don't know about HDR or immediately think of over-processed landscapes, you should be pleased that the current HDR relates to image

However the current front runner is Hybrid Log-Gamma (HLG) a version of HDR that was jointly developed by NHK and the BBC. HLG has a number of advantages but the main ones are that it is royalty-free and compatible with Standard Dynamic Range (SDR) displays. Hybrid Log-Gamma archives this backwards compatibility by combining two different

An HDR TV will need to recognise the logarithmic curve HLG uses - and at the time of writing there are no TVs out there right now that do this. However, most big-name manufacturers have confirmed that their 2017 sets will be HLG ready, with Samsung and LG also confirming that their 2016 HDR TVs will receive HLG support via a firmware update.

Static metadata. HDR10 is the most common and popular type of HDR, since it is an open standard and is used by a huge range of streaming services, including Netflix, Disney+, Apple TV+, and more. Also it is free to use for manufacturers, so it can be decoded by any HDR TV and streamed by any HDR streamer. HDR10 uses something called "static

I have an HDR TV which I think handles HLG, but no computer HDR monitor. I have a Sony camera which supports shooting HLG; of which I have no experience and am now learning. In any case, HLG, by definition, can be viewed on a TV without HLG support; I wanted to see what it looked like compared to my normal SLOG2/Pro footage which looks great.

Of some 137 linear TV providers, we count about 40% that offer HDR content. The vast majority (81%) of them use HLG, while 11% use PQ. With On-Demand services, particularly OTT streaming providers, the picture is almost perfectly mirrored: Of the 76% that offer HDR content, 88% use PQ while 12% use HLG. There are sensible reasons for these

Among the major HDR standards, the PQ-based formats (like HDR10 and Dolby Vision), both rely on metadata in order for the target display to know how to display the HDR content correctly. The difficulty in carrying such metadata along through all of the different devices and links, is one reason why HLG seems to be getting a bit more attention

While HDR10 and HDR10+ are specific formats of HDR video (along with HLG10 and Dolby Vision). So, for example, VP9 Profile 3 (HDR) supports 2 color depths (10 or 12 bit) and 2 transfer functions (PQ or HLG). But HDR10 implies 10-bits and PQ, while HLG10 implies 10-bits and HLG. Furthermore, HEVC Main 10 profile supports multiple transfer
