off screen screengrabs could do?As HDR becomes more prominent, we'll need a way to capture HDR and display it as intended. Right now screenshots aren't cutting it for HDR games.
Nopeoff screen screengrabs could do?
please explain. Tell me. To understand.Nope
Let's say that you are colour blind your whole life. You cannot see the colour purple. It doesn't matter how many different ways the colour purple is captured, you will never be able to see it until you are given a technology that allows you to visually see purple.please explain. Tell me. To understand.
thanks for the thoroughly detailed explanation. So a still photo can't capture the difference in a game connected to 2 different screens -side by side, one with HDR the other without HDR- and you need to actually see HDR with your own eyes in real time, right?Let's say that you are colour blind your whole life.

Like a pair of glasses for colour blind people would do.
That's like HDR.
If that analogy doesn't work. Think about music then.
You're whole life you can hear frequencies from 20Hz to ~20KHz. But when you listen to music on your ear phones the phones only have frequency response of 40Hz-16KHz. So aside from real life, you've never heard music close to your maximum hearing range.
And it doesn't matter how great the source of the music is, it doesn't matter if it's vinyl or digital or analog or has musical tons above your hearing range, because as long as you listen to music with those lower range ear phones that's all you will ever hear.
HDR is that. HDR increases the range in which you can see. You need an HDR TV to see HDR.

It'll show a difference but not how it looks in person. If you take a photo of a bright, sunny day and display it on a normal monitor, it's not bright to the eyes. So even taking an HDR photo of an HDR display, once you display that on a standard range display it'll lose its HDR. Not to mention off-screen photos don't look much like the real game anyway.thanks for the thoroughly detailed explanation.

excellent read. Thanks for sharing. I've been reading it these days and while I didn't have internet for a couple of days I had loaded the pages already and kept the PC in sleep mode so I gave it a thorough read.Camera "HDR" is usually a combination of an under exposed image and an overexposed image to resolve detail in bright areas and also in dark. Fundamentally it's still only showing information on the same scale, a very flat scale designed to print where luminance of a pixel is not needed.
The image only needs the colour of a pixel not it's brightness, and x and a y I guess, video has luminance Sona z axis and people talk of colour volume of a display this is all that combined.
In video HDR expands the colour range that can be described is increased over the old standard to closer that of photography I believe, and a massive increase in the luminance possible of the pixels within. A film camera to film HDR needs to capture 16 odd different exposures at the same time to create the content.
There is a very detailed guide to HDR and its production pipeline which although long is well worth a read, it details the formats as well as display technology and dispelled some common misconceptions

well, now you can take a HDR screengrab using Xbox Game Bar, which is enabled with the big circular button of the Xbox One gamepad -or with Windows key + G-. I explain it in more detail here; https://forum.beyond3d.com/threads/curved-monitors-with-high-hz.61542/page-3It'll show a difference but not how it looks in person.

An actual HDR data dump and image format is required. I see these exist but aren't standard. JPEG XR looks a good candidate with support native in Windows 10 - they just need to update the screen-grab APIs to support HDR (if they haven't already).
no, it doesnt. Everytime I tried, just like with the snipping tool and similar, the picture just look as if it was destroyed or someone used the eraser on most of the screengrab.I don't think it's valid to just take printscreens of HDR content. Does the clipboard save images with HDR?
nice read, can someone point me to well mastered HDR content, because so far I've seen in my light controled room was overly bright HDR.
Games often have basic configuration controls to dial it in to your TV and preferences. GT on the PS4 is supposed to look very natural and a great showing for HDR
Metro Exodus -pc version, consoles should be about the same- has one of the best implementations. The best I've seen yet.nice read, can someone point me to well mastered HDR content, because so far I've seen in my light controled room was overly bright HDR.
missed that video before, thanks for sharing. It's a good video to test HDR on and HDR off on your screen. HDR support on PC is still in its infancy compared to consoles.So it's tone mapped into sdr
I suppose Dolby Vision is the tightest controlled format, watching that should be as close to an intended as possible.
The quality of authoring if probably equal or better to TV specific implementation. Or that's the impression I get, especially for hdr10.
