HDR – what does it give us?
If you are shopping for a new TV set you will discover that a lot TV sets today support 4K UHD resolution and many of them also support some level of high dynamic range (HDR). This means that many new sets from now on will be compatible to show HDR films if available. HDR is not another 3D hype that will be gone in some years. HDR is here to stay and evolve! Technically, it is actually a paradigm shift, switching from the gamma correction transfer function to perceptual quantization (PQ).
