HDR Discussion Thread

A Dolby patent:
https://www.google.com/patents/US20120321273

"The metadata may provide information relating to: characteristics of a reference display used to edit the video data, characteristics of the environment in which the reference display is situated, characteristics of the edited image (e.g. luminance and gamut), characteristics of the viewing environment in which the display of the display subsystem is situated, etc.
In some embodiments, at least some of this information may be determined at the studio during post-production processing of the video data.
Parameters describing the environment in which the display of the display subsystem is situated. Such parameters may include, for example, ambient luminance and/or tone or color temperature.
Viewing environment metadata 225C may be used to guide processing of video data at block 208 and/or display configuration at block 210."

In keeping with cutting edge ^ themes, today, a first, cutting edge content creators working an ice hockey match at 100fps….





Perhaps you’ll see the recorded footage at an upcoming professional conference/show.

Anyway, heads-up Hollywood locals, for tomorrow evening at AMPAS on Vine -
https://www.eventbrite.com/e/do-you-...ts-33412367290

Get there on time as starting at 5 P.M. there will be a demo area filled with monitors from Sony, Panasonic, Eizo, Canon, Plura, Postium, TV Logic and Flanders Scientific.

Included in the discussion at 7 P.M. (which includes top drawer presenters) will be High Dynamic Range and Expanded Color Space.

Happy to see Hidden Figures now available on Ultra HD Blu-ray.

Keeping in mind also, that not all ‘jocks’ (see Appointments) are one dimensional either….http://math.mit.edu/~urschel/

Despite the complexity of the flow chart, it's still fascinating to consider the thought process of the designers.

Indeed.
Certainly requiring cognitive functioning, as opposed to the result of being manipulated thru the use of exciting/triggering primitive emotions by more nefarious designers…..https://forum.blu-ray.com/showthread...g#post13459679

The cover art ^ showing the women's attire reminds me…..for those who don’t read thee ARVO journals for things like the newest ways to replace dead retinal ganglion cells and confine themselves to less scientific sources of visual information, heads-up to a follow-up as to a topic which was raging online in 2015. See the JOV Featured article in the middle of the page entitled “Illumination assumptions account for individual differences in the perceptual interpretation of a profoundly ambiguous stimulus in the color domain: “The dress”….. http://arvojournals.org/index.aspx

Next visual dilemma, at least for those insistent upon a faithful reproduction of the Director’s original creative intent with movies, but due to a different etiology –

Not necessarily an HDR home deliverable, but before I forget, as I’ll be away at NAB during the series premier, a tie-in to the previously posted pic of the person I quoted – https://forum.blu-ray.com/showthread...n#post13434815

b.t.w., the ‘M’ part ^ of the newest under the radar color science acronym stands for millions, as later alluded to by Timo, the Dolby Staff Researcher.

Like Al says to Kat in Hidden Figures “….look beyond the numbers, look around them, thru them for answers to questions we don’t even know to ask.”. Ergo, Timo will explain in the future that by using an absolute color representation, as opposed to relative color representation (CIE L*a*b*), the color reproduction capabilities of different displays can be accurately compared against each other, which is a critical task for reviewing and designing display devices…..not to mention a vehicle for the marketing folks to ride.

I just recently purchased a 65" LG C6 oled and am coming from an2016 Vizio P series. I have all my components running through my Onkyo nr656, which I also just received. I have cable, Xbox one s and Oppo 203 all connected to the receiver and have a single hdmi cable running through my C6. I know LG recommends UHD deep color to be set to on, but can I leave this setting on all the time without any harm? I want to be able to have all my components running through my receiver and would prefer if possible not having to turn deep color on every time I go from watching a movie to cable and vice versa as I often like to check the status of a game quickly then go back to the movie. On my P series, I did not have to have deep color on at all, so I am a bit confused about it. Any insight if any negatives about leaving it on the all the time would be greatly appreciated.
