It is one of the large format cameras that has a bracketing button right on top of the camera. I use a Nikon D800 in my photography work. Le Gray used one negative for the sky, and another one with a longer exposure for the sea, and combined the two into one picture. He used this method to photograph seascapes showing both the sky and the sea, which were almost impossible at the time using standard methods, as the luminosity range was too extreme. The idea of using a number of exposures to assist in photographing an 'all over the map' range of luminosity was pioneered by Gustave Le Gray in the 1850s. The 3 photos are taken at different exposures, then blended together to make one photograph by using post processing techniques. Since HDR involves taking at least 3 photos of the same subject or area, more often than not a tripod is used to keep the camera in the same position, as well as stead. HDR is not suitable for every photographic situation, but can be used to make a better photo when: (1) the ratio of light to dark varies across the scene (for instance, a large landscape with many areas of light and dark) (2) portraits in sunlight (HDR can even out harsh shadows) (3) low-light or backlit scenes (HDR can brighten up the foreground). Dynamic Range is the ratio of light to dark in a photograph.

The movie will then take a large array of information, for example here is a single frameвЂ™s extra metadata.HDR stands for High Dynamic Range. HDR10+ is specifically for 10-bit video and up to 8K resolution. Videos that have HDR10+ support will generally include HDR10 static metadata as well. For example they will take MaxFALL as вЂњG(x,y)B(x,y)R(x,y)WP(x,y)L(max,min)вЂќ. 'side_data_type': 'Content light level metadata',Д®ncoders such as x265 (for HEVC / H.265) and rav1e (AV1) can support mastering display, and will take the arguments in a simplified format. 'side_data_type': 'Mastering display metadata', If you extract these metadata elements, stored in the videoвЂ™s SEI messages, it will look something like this: 'side_data_list': [ The Mastering Display consists of static Maximum Frame Average Light Level (MaxFALL) and Maximum Content Light Level (MaxCLL). HDR10 is built on top of HDR as a small set of information given to the video to tell the player the вЂњMastering Display Color VolumeвЂќ for the entire video. But first, lets go deeper into вЂњtrueвЂќ HDR options. However this is an issue for broadcasters who need to provide to older and newer hardware, thatвЂ™s where HLG comes into play.

This is not much of an issue for movies, as HDR is only currently on 4K Blu Rays, so the players have to support BT.2020. Stills taken from DolbyвЂ™s Glass Blowing Demo So now they uses a 10-bit or 12-bit pixel format and larger color space ( bt.2020) instead of the traditional 8-bit ( bt.709) to encompass a much larger array of color and light depth.

Well now that we got 10-bit videos, we also have room for more colors right? The UHD Alliance thought so too, so they set the standard requirements of UHD videos to be:

The standard curve generator for UHD movies is SMPTE ST 2084 but there is also HLG, discussed below. That means we need two things, more room to store information (aka 10-bit videos), and some kind of maths that can condense the usual steps into a gamma curve.

Whereas to capture more of the details in the darks, we would want something that has smaller steps of difference at lower light levels, but can be larger steps the brighter it gets. The human eye is a very sensitive to small changes in darkness, and the traditional range of brightness in 8-bit video is basically a staircase, each level of light the same distance away from the one before and after it. What HDR actually allows for is simply brighter brights, and darker darks. Companies like to slap it on just like they do with вЂњHDвЂќ if any of their stuff meets minimum requirements (and sometimes not.) HDR, aka High Dynamic Range has been overloaded to mean many things nowadays.
