Apple doesn't darken SDR to amplify HDR. They keep SDR the same brightness as it was before HDR showed up. It appears like SDR gets dimmer because of your perception of contrast, but it's not actually within a small margin of er

I think you're confusing which HDR is being used. HDR photography, the multi-expose combinations, was probably iPhone 5S but that still results in an SDR image. That's a completely different thing entirely. iPhones have not capt

No, it literally isn't. It's literally doing the opposite, it increases the display brightness in order to show the HDR content. The SDR content is dimmed proportional to the increase such that SDR has the same emitted brightn

There's many factors in play from what your SDR white point is at, how your OS handles HDR video, what the content contains, and finally what your brain is doing. HDR10(+) & Dolby Vision, for example, encode content at absolute lum

Trees and graphs serve useful roles, of course, but calling a linked list just a simpler version is a stretch. It'd be like calling an array a simplified B-tree. The simplification changes not just the implementation but also radically

You don't & generally shouldn't be in the first place, in any language. Linked lists are a very niche data structure, so generic code should ~never be using them. So it's a moot question. It's kinda like the compla

C++ is very definitely not just wrappers around C and it's pretty ridiculous to frame it like that. Or if you want to insist on that, then C doesn't exist, either, as it's just a few small abstractions over assembly.

"practical bicycles" is nebulous, vague, and always means whatever you want it to mean to claim to be right. Bicycles do not need precision bearings nor pneumatic tires, as proven by the fact that bicycles predate them by decades.
