UPDATE: Netflix will not be the only one in town HDR. Amazon has revealed that it will bring HDR content of his Prime instant video service later this year, starting with their own original content.
Talk of 4K TV has become ubiquitous, and if the hardware at CES 2015 was any indication, are aligned a variety of companies to ride on the momentum.
Several other home entertainment innovations was all over the living room, like LG Quantum Dot LED TV from Samsung or line of premium SUHD TVs that are supposed to update the existing Ultra HD standards.
But in the shadow of these talks improvements are due to another development - it's called High Dynamic Range, HDR, or which could awaken the next layer in the television equipment.
What is HDR?
High dynamic range is not entirely new, at least outside of television equipment. High-end cameras and the latest smartphone applications use HDR for higher quality images. By combining several photos taken in a single burst, HDR leaves less room for error, and in most lighting conditions, harvest striking results.
Separate images are taken at different exposures during the process. These called stations, and the amount of light from one to the other doubly. So while the first station is a very dark image, the end result is exceptionally bright and provides better lighting in the final photograph case.
HDR video, however, is shot with a broader scope - it detects dark shadows and brighter whites during the filming process. It's not really a combination of light and shade, but separates them even further, creating a wider range of possible colors - HDR TVs are the only option for the image on the screen of Justice .
Some cameras have a different number of stops in the use of HDR, but overall, the method allows for pictures, not to seize the regular digital photograph of the situation. HDR brings media close to what the human eye sees, and in this way to create realistic images of scenes is bleached sunlight to night shooting in the streets of the city.
How is the HDR effect on the viewing experience?
4K is the biggest trend in the display hardware today, and for good reason - it offers four times the normal amount of pixels than 1080p, finer detail and presented better textures. Companies like Sony, Samsung, Panasonic and LG are busy, 4K their televisions on the shelves this year, and improvements in hardware allows more viewers to watch content from the increased resolution.
But HDR is because of the way it actually changes the picture quite different. The colors are more vivid, blacks are deeper objects more pronounced. The colors are also exaggerated, alternating between hot and cold in the same image.
The key here is Brightness: The majority of television today have a typical brightness of 400 nits (The luminance unit), while others take the plunge to about 750 in 2014 HDR TVs, however, have a maximum of about 1000 nit. This increase means the difference between normal outdoor scenes and realistic.
scenes of the desert turned in movies HDR-compatible cameras much clearer, with its colors and brightness rather to the actual sun. inequality winter shots higher between the building and its surroundings this snow. During the 4K resolution increases the quality of the displayed image increases color HDR, contrast, and around realism.
Once HDR is a standard viewing households, more and more film and television crews will probably start shooting with HDR-compatible cameras.
