It's not particularly uncommon for an article about a scientific breakthrough to be almost satirically misleading.

If this really works, for instance, it could be a revolution in television design; far better than the quantum dot technology that people are adapting now. But, if the article was about TVs then it the responses would all go in a million directions (comparisons to plasma, talking about energy star ratings, whatever).

Back in the 50's, it was pretty common for scientists doing nuclear weapons research to talk about things that would happen in stars of unconventional configurations; when they were really broadcasting to the USSR that the US scientists had solved problems with hydrogen bombs that put them far ahead.

Go to a friends house and turn on their flat-panel TV. 99% of the time, it will have frame-rate interpolation turned on; which basically means that any content they see on that TV will be at 60 or 120 Hz. Even movies shot at 24.

More and more often as I do presentations to executives, they don't understand why my TVs look so "juddery" compared to what they expect -- it's because at home they're watching everything at 120Hz.

So no -- most people are happy with high frame rate most of the time, and that percentage is getting larger quickly. I am a big 24fps fan, but I believe the days are numbered.

The Dolby Vision TVs will have reasonable controls to set brightness and contrast, but one of the selling points to the studios is that we will strive to maintain the artistic intent of the original. The blacks will be black, the whites will be white, and there will be an unprecedented (but realistic) amount of contrast.

It turns out that in high dynamic range content creation, the most important thing is not that the picture be brighter overall; but that there is an increased range between midtones and highlights. In current production, skin tones are set to about half the maximum brightness in the scene. This means that the brightest things in the image (say, a glint off of a chrome bumper) can only be twice that bright; where in real life it's more that 100 times that bright. So, leaving the midtones about where they are, and giving brighter highlights makes the image look better in a way that you have to see to understand. Or, you can just look out the window.

As the article states, two of the most important changes in this standard are high dynamic range (HDR) and wider color gamut (Rec. 2020) images. I have been working on this with Dolby Laboratories for the last few years, and whenever we bring in movie directors, cinematographers, colorists, or studio executives to see our ridiculously HDR wide-color-gamut display, their jaws hit the floor. The ability to reproduce the dynamic range and color gamut of real life is breathtaking. One of the studio executives, when asked if she could see the difference said "Do I look like a potted palm?"

You will see the difference, and you'll be able to see it from across the room. HDR and wide color gamut combined with UHD resolution is a revolution.

I know this sounds like a sales pitch (ok, it is!) but I've been working in the film business for 30 years before I started working on this; I know what creatives want, and this is it. I spent that time working on CG visual effects, and I think that HDR will have a comparable impact on filmmaking that VFX did.

The Dolby Cinema theaters opening in the next few months will have similar extreme dynamic range and wide color gamut. They look astonishingly better as well.

Wait and see. It's coming, and it's not far away.

if the same data has been used to claim a warming trend and the same data is used to say otherwise I'd call that invalid data.

The same data has been used to claim men landed on the moon, and that the moon landing was a hoax. Therefore all data related to the moon landing should then be ignored. As it's proven flawed on both counts.

earth is primarily a self regulating eco-system leading to stability

Gaia is living, breathing, self stabilizing organism. Gaia actively maintains optimum conditions for live to thrive. If the sun fluctuates hotter, Gaia will keep us cool. If the sun fluctuates cooler, Gaia will keep us warm. We have released two quadrillion pounds (2,000,000,000,000,000) of CO2 into the atmosphere and the laws of physics say that will trap heat.... and Gaia will.... umm I dunno... but Gaia will do it's super-smart-Gaia-thing to to actively counter it and keep us in a loving protective embrace of shielded stability. If we have a nuclear war, Gaia will cleanse the environment and protect us from that nasty radiation-stuff. Gaia loves all life, gaia loves us and protects us. Gaia loves broadway shows and long walks on the beach. Gaia has profiles on eHarmony.com and JDate.com.
