What is HDR? – The New Technology Explained

The Inter BEE 2015 technology exhibition that took place near Tokyo ended earlier this week, but during my visit two topics where very evident. HDR and 8K! While I intend to dedicate a separate news post to 8K, HDR is the more “relevant and upcoming technology” that might affect our professional lives soon.

But what is HDR? The new “high dynamic range” technology started to emerge in a more prominent way during last NAB show in Las Vegas (April) and now, half a year later, after looking at the Japanese domestic market, there is no doubt that it will find its way to our homes sooner rather then later.

To grasp the impact of the technology you simply have to look at a video which was shot and played back on an HDR monitor in order to appreciate the enhanced clarity and depth you are getting. It is almost like looking at a three dimensional picture without the need of 3D glasses, but in fact it is something else than 3D entirely. If I had to describe “what is HDR” in a sentence, I would say the new technology brings us a higher dynamic range viewing experience, richer colours, and more realistic images, than we’ve been used to. The displays are a lot brighter in the highlights, thus giving you a more realistic experience when it comes to light distribution across an image.

During Inter BEE I had a chance to talk to Ishii-san who took the time to highlight some of the benefits we should expect from embracing the new technology. According to Mr. Ishii, implementing HDR on video cameras is almost done, as sensor dynamic range constantly increases, but it’s the displays that are lagging behind. Leading companies like Dolby laboratories together with American and Japanese manufacturers are trying to standardize the technology and hopefully they will be done soon.

If you already had a chance to see some video demonstrations of HDR, please share your experience in the comments and let us know what you think about the emerging technology.

I say NO to the over-bright Dolby Vision tech! I don’t know what to do to dim the brightness down on my TV and they want to boost it several times in intensity, absolutely not!

HDR imagery is used since the late 80s in computer generated images for texturing environments and is used for many years that way. I think if they truly want to implement HDR into cameras and displays than either you need sunglasses if you sit in front of an HDR display that can reproduce bright lights, but I think when HDR is processed so you can watch it “normally” it does not look real, but comical regarding shading and colors. For my opinion HDR is not really usable as a end-user imaging system. It would be better to implement higher bit-depths to the displays rather than making them able to display a brighter image to simulate “real” light brightness.

Strange echoes of what happened with still imaging back in the 80’s and 90’s. Technical solutions to what are in fact perceptual issues. Psychologically, there is so much that is wrong with the way such things as contrast ratios and colour intensity are pursued beyond aesthetics.
