Consumer Technology Association sets official standard for 8K UHD TVs

We all know that:

For a couch potatoe SD and HD is enough.

For a cinefile color and contrast is more important than 8K resolution.

For bandwidth, HD is a much more effecient resolution for video. Even 4K feels modest compared to 8K.
 
For photography, 8K screens change everything.

I like the look of 8K for documentary.

Video cameras now really have to up the specs in dynamic range and color fidelity, as 8K resolution really commands more scrutiny than HD, or even 4K. Color standards and playback standards for display also need to be refined.
 
Meanwhile, almost everything you produce is viewed at 720p or 1080p on 4" screens. Millenials and Gen Xers, as an audience, aren't buying
65" 8K sets. Old, demographically less significant audiences are in smaller and smaller numbers.

You can debate the relative merits of 4K vs. 8K adoption until the cows come home but please just acknowledge that resolution
wars are nothing but a necessary function of selling new gear, whether its to pro content creators or to consumers. It certainly
isn't being driven by clients, who are largely still requesting or even requiring 1080 delivery. We exist in a vacuum!

You are right.

Regardless, 8K is welcome for displaying photographs. I doubt it will effect how ‘Casablanca’ on Bluray looks.

I think the harder question way down the line is if consumers will see any advantage to beyond 8K resolution televisions in the home. That one is a trickier conversation considering the average large screen TV sizes.

Agreed!

Even on the 80” 8K demo tv’s at tradeshows, the pixels are small enough to not notice even fairly close up.

8K enters the diminishing returns era of resolution.

Hopefully this also means improvements on standars and other areas of IQ. Highlight clipping in 8K is so much uglier than HD. Should cause more scrutiny on image making.
 
An 8K screen is a display.

Hopefully we can see this as a format agnostic device, rather than feeling like we have to shoot everything in 8K raw.
 
If video screens were only ever going to be used for watching Saturday Night Live from the couch on a 60" screen 8K would obviously be a pathetic joke. But wall size screens will probably be common at some point, and for architectural and installation projects 8K will be a blessing.

We got 8K now though.

So your premise is that hopefully you'll get this time with 8k what you didn't get with 4k, better pixels. 4K already entered the diminishing returns era of resolution, just at smaller screen sizes and farther distances, because as Steve Yedlin commented, "Once you have enough pixels that you can longer see them, there is no benefit from having more pixels, and we have already reached that point."

I was at the scene, as it were, when first 70" rear projection TV appeared (1990, Mitsubishi) and consumers were in awe. And Mitsubishi couldn't make enough of them for years. A typical tube TV was then 26-27, 31 was rare and 35's were ultra high end ($2,500-$3,500, depending on a model and style). Then Mistubishi released what was then advertised as 700 lines of resolution 45 and 50 and those were quickly sold out. The same went for 60 and 70, priced at $4,000 and $6,000 respectively.

And nowadays one can get a 4K 75" flat screen for under a grand. Home IMAX, here we come.

When you playback your photographs on an 8K screen, then make your assesment.


But yes, 8K is better than 4K for a lot of reasons beyond watching traditional shows and movies.

Let's say your 8K photograph assessment is 100 percent true, will this be a big enough difference to get joe consumer to buy a new 8K TV ?

From my own experience, friends and family look at their photos on their phones and tablets, and pretty much never look at them on their TV sets.

I think you just answered your own question.

Sounds about right.

8K raw is about 33.2 megapixels, right? That means, in order to get true 4:4:4 color, we need about 100megapixels in Panavision Genesis style rgb pattern. Medium format film making, here we come.
 
It is pretty obvious that professional photographers are still getting paid work with cameras that have less than 50mp sensors. Just depends on what they are shooting for.

Hopefully, video can start adopting a similar mentality. We don’t need to shoot 8K, just because 8k tv’s exist. Just like photographers don’t need to shoot in whatever the highest resolution printers are.
