What is HDR? What does High Dynamic Range Mean?
In this article, we will discuss the High Dynamic Range, HDR, what it does, how it works, in detail in TV and smartphone cameras.
With the advancement of technology, it has entered our lives in many new terms thanks to the new technological devices. One of them is HDR. We encounter these terms when buying TV or on the cameras of the phones, we use the most. So what is HDR? What does HDR do?
What is HDR?
HDR, which stands for High Dynamic Range, or High Dynamic Range, is an exposure technique applied on photographs and a broadcast format on televisions. HDR means taking the same frame more than once with different light intensity and overlapping these frames in computer environment.
How does HDR work, what does it do?
When taking a picture or video, if a strong light strikes the frame, the HDR feature corrects the image to improve shooting quality.
HDR, as the name suggests, is a method that aims to add more “dynamic range” to photos, where dynamic range is the ratio of light in a photo to darkness. Instead of just taking one photo, HDR uses three photos taken at different exposures. You can then use the image editing software to put these three images together and highlight the best parts of each photo.
What is HDR on TV?
If a television or monitor or mobile is HDR compatible, it means that you are seeing an overlay of colors in the image you see on the screen. Thanks to these many different shades, the image you watch become a reality as a result of depth and depth.
For example, in a very dark cave scene, HDR TVs show the texture of the cave walls as well as their appearance. In a scene with a yacht above the ocean, one can see clearly that the sun’s rays shine independently of the background where the sun shines.
The most important feature of an HDR compatible television is its brightness range. A television that can deliver higher and lower brightness than conventional televisions or monitors allows you to see all of the colors and light changes in the image.
There are several HDR standards, but ‘HDR10’ is the most widely used. Recently, a new technology called HDR10 + has been introduced, and the difference between it and HDR10 is whether dynamic metadata * or static metadata is used.
Dynamic HDR technology means applying metadata to each scene and then delivering a more optimized image quality compared to static HDR technology.
