I was mainly looking for HDR support for playing of video's where with HDR active the colours are richer and more vibrant.On Sun, 2024-11-10 at 01:29 +0000, Steve Underwood wrote:I don't think anyone has mentioned which graphics hardware they are using. I'm not sure the HDR support is equal amongst them.As someone who's worked in video production since the 1980s, I've tried it on my TVs, with appropriate video sources, and I can't say I want to use it. I imagine it's worse with computing. Coming from a photographic and video production background, our goal always was to get appropriate skin-tone reproduction, then dress and light your scenery to compliment it. That's harder to do outdoors, and can involve complicated lighting of people against sunlight, to get a scene into a range of brightnesses that the camera (or film) can handle. To some creators, HDR is simply more individual steps between completely black and fully illuminated. To others, it was your original contrast range and then being able to go even brighter. So you're forever having to fiddle with your brightness and contrast to get a reasonable image, depending on what you're watching. The first approach takes the visible quantising out of some images, where a bright spot in a scene would have had a bright spot with obvious concentric rings getting brighter around it, as there wasn't enough bits to do a smooth transition, to making it look natural with no visible steps. The second approach ends up with occasional scenery that's just too damn bright to look at, either because outdoors during they day is much brighter than indoors, and they've tried to reproduce that. Or they just wind everything up so that something always hits peak brightness (just like the audio loudness wars), making things very harsh to the eyes. And the converse, someone decides indoors is dark and should be naturally so, to the point that you can't see anything. Take that over to computing, and how are people going to make use of it? Are they going to set up the display so that photographic imagery looks natural? And are they, then, going to set up web-page and word- processor white page backgrounds to be blindingly 100% bright, as well, like things are now with standard dynamic ranges, or are they going to tame that down to something more appropriate?

Steve
