If you want to avoid eye pain then you want caps on how much brightness can be in what percent of the image, not to throw the baby out with the bathwater and disable it entirely.
And if you're speaking from iphone experience, my understanding is the main problem there isn't extra bright things in the image, it's the renderer ignoring your brightness settings when HDR shows up, which is obviously stupid and not a problem with HDR in general.
- adgjlsfhk1 1y agoit actually is somewhat an HDR problem because the HDR standards made some dumb choices. SDR standardizes relative brightness, but HDR uses absolute brightness even though that's an obviously dumb idea and in practice no one with a brain actually implements it.
- mort96 1y agoIf the brightness cap of the HDR image is full SDR brightness, what value remains in HDR? As far as I can see, it's all bath water, no baby
- Dylan16807 1y ago> If the brightness cap of the HDR image is full SDR brightness, what value remains in HDR? If you set #ffffff to be a comfortable max, then that would be the brightness cap for HDR flares that fill the entire screen. But filling the entire screen like that rarely happens. Smaller flares would have a higher cap. For example, let's say an HDR scene has an average brightness that's 55% of #ffffff, but a tenth of the screen is up at 200% of #ffffff. That should give you a visually impressive boosted range without blinding you.
- mort96 1y agoOh. I don't want the ability for 10% of the screen to be so bright it hurts my eyes. That's the exact thing I want to avoid. I don't understand why you think your suggestion would help. I want SDR FFFFFF to be the brightest any part of my screen goes to, because that's what I've configured to be at a comfortable value using my OS brightness controls.
- Dylan16807 1y agoI strongly doubt that the brightness to hurt your eyes is the same for 10% of the screen and 100% of the screen. I am not suggesting eye hurting. The opposite really, I'm suggesting a curve that stays similarly comfortable at all sizes.
- mort96 1y agoI don't want any one part of my screen to be a stupidly bright point light. It's not just the total amount of photons that matters.
- Dylan16807 1y agoIt is not just the total amount. But it's not the brightest spot either. It's in between.
- mort96 1y agoI just don't want your "in between" "only hurt my eyes a little" solution. I don't see how that's so hard to understand. I set my brightness so that SDR FFFFFF is a comfortable max brightness. I don't understand why web content should be allowed to go brighter than that.
- Dylan16807 1y agoI'm suggesting something that WON'T hurt your eyes. I don't see how that's so hard to understand. You set a comfortable max brightness for the entire screen. Comfortable max brightness for small parts of the screen is a different brightness. Comfortable. NO eye hurting.
- mort96 1y agoIt's still uncomfortable to have 10% of the screen get ridiculously bright.
