High-dynamic-range (HDR)
High-dynamic-range (HDR) imaging is a technique that captures a greater range of luminosity than a traditional camera, which allows for images with more depth and richer colors. HDR video is a relatively new trend that makes colors more vibrant and realistic. You can see the difference between HDR and normal video by comparing a scene shot in daylight to one shot with an overcast sky. The colors in the daylight scene are brighter and more vivid, while the colors in the overcast scene are duller.
In PC and console gaming, HDR has become a fixture in recent years with the latest generations of consoles all supporting HDR@4K, including PlayStation 4/5 models, Xbox Series S/X and others. Note that you will need to have an HDR-capable display to take advantage of this technology.
