What is HDR?
HDR (High Dynamic Range) looks set to be the next big thing in the television world. It's the next stage in TV technology development and the natural next step and progression from 4k Ultra HD. Here is everything you should know about what HDR is, how it works and why it is so good.
HDR looks set to raise the bar higher than ever before when it comes to contrast and colour. If 4k Ultra HD was all about increasing the number of pixels on screen (to a whopping 8 million) then HDR is all about increasing the quality of the pixels themselves. Sony, leading the way with HDR, has ensured that its HDR TVs are compatible with 4k too so the very best of both worlds can be enjoyed - and Sony's lead is bound to be followed by other manufacturers.
How does it work?
Essentially, HDR increases the colour accuracy and the contrast ratio of the picture display. This makes blacks deeper, lights brighter and brings images to life like never before. In some circles, the experience has been likened to 3D.
What's the effect of HDR?
HDR is actually not absolutely new on the scene. You can find top-end cameras and even smartphone apps on the market that use the same technology. In photography, HDR takes several images in one go. These are all basically separate photos taken at differing exposures. Light is doubled from one to another and the effect of an extremely dark shot followed by an incredibly light one improves the overall colour considerably. In a similar way, HDR video separates the lights and darks to create a vast array of colours.
The future is coming and that future does look like it's with HDR. As the natural progression and development to 4k, HDR will almost certainly be the pictures on our screen sometime soon.
