HDR10

HDR (High Dynamic Range) is a technology  that presents picture in a wider range of brightness, contrast and colors in order to make them look more natural on a HDR enabled phone or TV. HDR10 is the current industry standard for high dynamic range. HDR is a video technology that allows film makers and content creators to produce and present video in a wider range of brightness, contrast and color, the result of which is so dramatic, that when you watch it on a good HDR compatible TV, you would feel the touch of a cinematic quality right on your small screen.

It is much more easier to understand HDR for a photographer. When you expose an image considering a well lit spot in the frame, The places that are not so well lit gets lost since there is not much data available. In photography you handle such a scenario with multiple shots with varied exposure compensation and then combine all the data into a single image, so that it has all the data from the well lit to not so well lit parts of the frame. These days most of the phones have a HDR mode on them to click photos.

2 types of HDR formats:
a. Static formats:

1. HLG
2. HDR10
The static formats store HDR data at a single point for the whole movie and is determined only once for the whole show. It does not vary scene by scene.

b. Dynamic formats:
1. Advanced HDR (by Technicolor)
2. HDR10+ (Partly by Samsung) - This also is a license-free format
3. Dolby Vision (by Dolby Labs)

The dynamic formats renders on the go i.e. these formats can adapt as you watch. It will boost certain elements or sometimes reduce depending on the scene, and mind you, this happens frame by frame. So you can imagine the quality of such a video. Undoubtedly HDR format has been a big leap in the video quality. 

Remember HDR10 is a static HDR format while HDR10+ is a dynamic one.
