Talk:DCI-P3

Incorrect Stated Whitepoint

DCI-P3 whitepoint stated as being D65 is incorrect: it is a specific whitepoint closer to 6300K and based on a Xenon Arc Lamp with xy chromaticity coordinates as follow: (0.314, 0.351)

DCI-P3 can use more than one white point and the one that will be used for consumer video will be DCI-P3 D65. --GrandDrake (talk) 18:56, 26 March 2016 (UTC)

That did not age well. 2A00:1370:812D:2909:E983:ADF0:3065:12E3 (talk) 05:57, 21 October 2020 (UTC)

Incorrect references to "color space" in picture box caption

The caption to the picture box at the top of the article repeatedely refers to "color space" even though the image is of a chromaticity diagram. Chromaticity diagrams most certainly do not depict color spaces, nor are chromaticities color spaces themselves, though they can (and frequently are) used to provide a portion of the definition of the primaries and white point in RGB color spaces. I have accordingly edited the text to be more factually accurate. Lovibond (talk) 17:23, 13 February 2017 (UTC)

How does it compare to ARGB?

Is DCI-P3 a subset of Adobe RGB?--146.52.211.5 (talk) 10:54, 2 July 2017 (UTC)

Neither the P3 gamut nor the Adobe RGB gamut is fully contained within the other. --2620:0:1000:2110:5C1B:875C:DC97:EF6C (talk) 22:01, 27 December 2018 (UTC)

iPad Pro 10.5” supports it too

We need 3D gamut image

As in here http://static.astramael.com/1/colorsync-3dplot.mp4 Valery Zapolodov (talk) 02:42, 24 January 2022 (UTC)

Valery Zapolodov, File:SRGB_gamut_within_CIELAB_color_space_mesh.webm (with source code) from SharkD might be a good place to start. I think it's something about cspace_other somewhere that you need to change... Artoria2e5 🌉 08:11, 26 July 2023 (UTC)

Can we describe P3 coverage as Calman and rtings do it?

I.e. from here https://www.rtings.com/tv/reviews/lg/c9-oled now if you compare with this https://www.rtings.com/tv/reviews/lg/g1-oled ? Valery Zapolodov (talk) 02:46, 24 January 2022 (UTC)

Does anyone know what actually happened to power issue in

Cleanup tags

This article's clean up tags had overly detailed explanations, added by User:A Shortfall Of Gravitas. I am moving the explanations here to remove clutter from the actual article.

Copy edit tag

• Awkward phrasing; it's like a mixture between Yoda and auto-translate throughout. Sentences like "In September 2014, introduced during a fair trade Photokina in Germany the CG-318 - the first professional 4K monitor with supporting of P3 color space." are readable but not proper English. Others are much worse, too much for me to being doing having wanting tackle in past future now moment.

Update tag

• Talks about DCI-P3 possibly being used in the future for home cinema (not P3-D65, and using an article as a reference that shows that godawfully jpeg-artifacted "is this dress blue or gold" meme from years back as an example of something it isn't, which should immediately discredit it)... P3 D65 in BT.2020 primaries are used on a huge % of UHD BluRays, it's practically a requirement for an HDR10 display.

Overly detailled tag

• There are far too many products to make listing those that claim support here either relevant or possible to be done in any kind of complete manner (it's missing at least 4 displays / devices I own that cover the whole colorspace and I wasn't even buying them because they were supposed to support it, they just happen to), the whole list should be removed.

Hi @A Shortfall Of Gravitas: No doubt this article was a hot mess, Wiki Color articles seem to be the victim of some sort of russian discord campaign, LOL! I did one fairly complete revision, but I left the issues template at the top of the article as there are probably a few more bits to fix, such as possibly reducing jargon, but I need fresh eyes to be objective. Myndex (talk) 11:55, 3 April 2022 (UTC)

Do you see russian collusion in the room right now? Article is a hot mess now after you ruined it. 2A00:1370:8184:164:49D1:BA8C:B200:C381 (talk) 03:49, 12 April 2022 (UTC)

Edit war with Russia

The entirety of the color space related pages have been under siege by some number of russians, clearly english is not their first language, and they do place their colloquial syntax here in the American english related pages, and it is incorrect. What can we do about this problem? Most recently I corrected the formatting of DCI-P3, and again, one of them reverted that edit.

They mostly use anonymous IP addresses. Do we need to protect these pages?Myndex (talk) 06:59, 23 April 2022 (UTC)

This is no politics section, go there libtard. 2A00:1370:8184:164:7D53:F8E0:4BCD:B758 (talk) 22:07, 23 April 2022 (UTC)

How about you stay on Russian Wikipedia and leave the English Wikipedia to native English speakers, and importantly, stop vandalizing these pages with your nonsense. Myndex (talk) 02:43, 24 April 2022 (UTC)

Some weird turf war (cold war? ice turf?) mentality going on here. Some folks spoke choppy English (e.g. "early production" does not sound like it's about displays capable of a useful fraction of P3) for sure, but to assume bad faith is a bit too far.

• The device spaghetti is not caused by some Russian dude. It was started by User:61.238.78.220, which is a... Hong Kong IP. Well, back then it was new and useful.
• A number of intervening edits added more devices. You can see that people took the list seriously even on this talk page: there's people asking why a certain iPad model wasn't listed.
• "Fair trade Photokina" is due to a Japanese guy. Most of the account's edits were helpful, or at least trying to be. This person's draft page shows the same "yoda phrasing" or whatever you call it, but that's just what happens with language barriers. (Japanese–English machine translation is also terrible before DeepL. With non-native speakers you sometimes genuinely can't tell if they are using an outdated machine translation program or actually cobbling words together from a dictionary using their limited understanding of the syntax.)
• The one guy with a Russian name, Valery Zapolodov, is actually quite good at English!
• 2A00 is a Russian IP, but their edits are mostly positive in terms of phrasing. What you did with the P3-D60 part of the table is very wrong.

--Artoria2e5 🌉 08:32, 26 July 2023 (UTC)

@Artoria2e5 Regarding your statement "What you did with the P3-D60 part of the table is very wrong." No it wasn't. The changes made by user 2A00:1370:8184:164... were/are factually incorrect and have no support by reference nor cite. There is no such thing as "ACES Cinema" and there is no such thing as "D60" (not a defined CIE D series illuminant). This is the kind of corruption of information (subtle or not) that I am talking about.

Here is an authoritative list of ACES spaces: https://acescentral.com/knowledge-base-2/aces-working-spaces/

Which are ACES2065-1, ACEScc, ACEScct, ACEScg, ACESproxy

Second, your listing of irrelevant edits does nothing to refute my conclusions, and I'm not talking about "english" I'm talking about corruption of information, and ad hominem attacks/shade/obstruction on vision science experts contributing to Wikipedia. The corrupt information may not be immediately obvious, except to SMEs that have been dealing with this garbage.

Considering the ad-hominems this person is flinging directly at me (and others), as seen above and against Wiki policy, it is clear they are trolling here. User 2A00:1370:8184:164... appears to be Valery who seems to be trying to hide the more egregious garbage behind these anonymized v6 IP addresses when he is being more disruptive that usual. If you take a moment and look at his TALK page you'll see that he is disruptive all over Wikipedia, and not just this article. Myndex talk   02:32, 20 July 2024 (UTC)
