Originally posted by LeeRunge I don’t know how you feel about, or others here, but I would love to see something like AirPlay for our DSLR’s or other cameras, espiecially with 8k TV’s with 33 megapixel displays showing up now and in the future. The ability to have friends of family around and do a slideshow presentation like we did in the past with good storytelling is still a great way to share adventures I think. Something like a samsung frame in 8k would be really pretty cool to do that with.
I was sucked into the "I need this D800 for the coming 4k TVs logic back when Jsherman was on the forum. It was one of his justifications. It was complete nonsense. On 4k, 1920 x1080p is indistinguishable from 4k video at a normal viewing distance. I have some 4k video from my ZS100, it looks great but file sizes make them less than desirable, and as I said, on my 4k TV they are pretty much indistinguishable at normal viewing distance. Remember, the larger the TV, the further you have to sit from it to avoid eye strain and you lose huge amount of detail just because of the 5 feet or more distance away from the screen. Peak human visual acuity s measure at 8 inches, and it falls off quickly, even by 18 inches.
Fool me once , shame on you (are you listening Jsherman?) Fool me twice, shame on me. The "upgrade for 4k" was a no go, I expect the "upgrade for 8k will be as well. A true 8k TV would be a 40 MP file for a still image. There's simply nothing we can do now to prepare for that. And I'm guessing even on 8k video , at a normal viewing distance, a 1920 x 1080 will be sufficient.
Last time I went into this issue I was ambushed with information I suspected was bogus but couldn't refute. This time, I have some experience with the issue.
Don't get me wrong, I love 4k for stills. But even then, when I have my computer running and the output is 1920x1080 (10 year old iMac,) once you get 3 feet or 4 feet away, (recommended distance for minimizing eyestrain is 6 feet) I can't tell the difference between when the same image comes up on my desktop, and when the same image comes up at 3840x 2160 on a sideshow image that runs from a data stick on my TV, of course if I walk up to the screen there's a huge difference, but I can't see the whole screen all at once. But at 6 feet, sitting in the lazy boy, there is no noticeable difference. It is always funny, Tess sitting in the Lazy Boy 6 feet away) says, "that's a really nice image", me standing at the computer keyboard right in front of the screen thinks, "that image looks like crap."
By the same token, I'm done with prissy dudes who claim they have to be able to walk right up to the image and it still has to look like a print done at 300 DPI. The topic has drawn extensive comment from some very ridiculous people trying to impress us with how high their picture viewing standards are, but who couldn't take a decent picture to save their lives. I think they believe that if they take a really technically impressive picture people will go "wow"... they don't but that must be what they think. Fact is, people go "wow" because of great composition. Most times, resolution is not a factor. I see the high res thing as a compensation for not very good composition skills, unless you're talking 8x10 great compositions by people like Adams, Avedon, etc. shooting 8x10 film. Their pictures look great small, but they look more impressive big.You walk up to an Avedon portrait, museum quality, and you feel like you're looking at the subject's face. Digital as yet can't match that.
That's an arguments for the iPhone by the way. For 4k TV 12 MP is fine. Maybe not until some kind of diffraction solution is found, I looked at the images from the first link, at close to 4k, and it was simply unacceptable, from any distance. But my 12 MP Q, K-x and Optio W90 files look just fine.
If you are really concerend about 8k TV, a 645z is the minimum and a D850 is barely acceptable. Phones don't even get into the conversation.
Given our experience with 4k TV, I'm not even sure 8k will be viable option in my life time, if ever. I suspect it will thrive in commercial applications, like a slide show or movie for a theatre full of people, not for home use. For 8 people sitting in my living room, 4k is excellent, and probably even overkill.
