What is HDR, anyway?

"we finally explain what HDR actually means"

Then spends 2/3rds of the article on a tone mapping expedition, only to not address the elephant in the room, that is the almost complete absence of predictable color management in consumer-grade digital environments.

UIs are hardly ever tested in HDR: I don't want my subtitles to burn out my eyes in actual HDR display.

It is here, where you, the consumer, are as vulnerable to light in a proper dark environment for movie watching, as when raising the window curtains on a bright summer morning. (That brightness abuse by content is actually discussed here)

Dolby Vision and Apple have the lead here as a closed platforms, on the web it's simply not predictably possible yet.

Best hope is the efforts of the Color on the Web Community Group from my impression.

No. Because it's written for the many casual photographers we've spoken with who are confused and asked for an explainer.

That's because this post is about HDR and not color management, which is different topic.

On the HN frontpage, people are likely thinking of one of at least three things:

HDR as display tech (hardware)

HDR as wide gamut data format (content)

HDR as tone mapping (processing)

...

So when the first paragraph says we finally explain what HDR actually means, it set me off on the wrong foot—it comes across pretty strongly for a term that’s notoriously context-dependent. Especially in a blog post that reads like a general explainer rather than a direct Q&A response when not coming through your apps channels.

Then followed up by The first HDR is the "HDR mode" introduced to the iPhone camera in 2010. caused me to write the comment.

For people over 35 with even the faintest interest in photography, the first exposure to the HDR acronym probably didn’t arrive with the iPhone in 2010, but HDR IS equivalent to Photomatix style tone mapping starting in 2005 as even mentioned later. The ambiguity of the term is a given now. I think it's futile to insist or police one meaning other the other in non-scientific informal communication, just use more specific terminology.

So the correlation of what HDR means or what sentiment it evokes in people by age group and self-assesed photography skill might be something worthwhile to explore.

The post get's a lot better after that. That said, I really did enjoy the depth. The dive into the classic dodge and burn and the linked YouTube piece. One explainer at a time makes sense—and tone mapping is a good place to start. Even tone mapping is fine in moderation :)

Often, we don't get that and this topic, plus my relative ignorance on it, welcomed the post as written.
