The screen doesn't literally dim, but my experience is that the screen suddenly dims because this one part gets so much brighter than the pure SDR white it's surrounded by.
I'm not talking about this in the context of watching long videos or something, but when just browsing through stuff on sites like Reddit. I'll be clicking on the "expand image" button on a series of posts (using the old reddit design) and then suddenly one of them is a HDR video which makes the rest of the screen appear to dim until I close it. So we're not talking about "especially bright scenes". And I'm sure that if I fullscreened the video and the whole screen was covered by that single piece of HDR media, it would look alright.
My guess is that those videos are filmed on an iPhone in HDR mode.
- Dylan16807 3y agoSomething has gone wrong in the calibration then. A normal scene shouldn't outshine normal windows. It's not a problem inherent to HDR.
- mort96 3y agoWhat is the “correct” brightness to a video of the outside on a bright sunny day compared to the SDR GUI elements? What if the sun is in frame?
- Dylan16807 3y agoI won't pretend to be an expert, but I'd say a nice daylit scene should almost certainly not be brighter than SDR white. If the sun is in frame, it should be very very bright, but it shouldn't be big enough to cause a problem. If someone embeds a video of the sun then they're trolling you.
- mort96 3y agoI mean I believe it's mostly just taking pictures or videos outside on their iPhones, which I believe will automatically capture in HDR if it's bright enough. I seriously doubt that people who upload some random picture they took outside to Reddit are intentionally trolling people who happen to use a device with an HDR screen.
- Dylan16807 3y ago> I seriously doubt that people who upload some random picture they took outside to Reddit are intentionally trolling people who happen to use a device with an HDR screen. Right. Those aren't pictures of the sun. I'm saying Apple's code is doing the wrong thing. Apple calibrated things wrong.
- mort96 3y agoThe sun can end up in frame in a video taken outside without it meaning that the person taking the video or uploading it to social media is "trolling" is my point.
- Dylan16807 3y agoI agree, but that has nothing to do with what I was saying. I specifically said that a sun at normal size wouldn't be a problem. I mentioned full-frame sun as a totally separate scenario just to be thorough.
