> But even then, the sentence in question doesn’t use the abbreviation

Yes it does. Why are you still looking at a different sentence than the one I quoted??

HDR in this context isn’t referring to just any dynamic range. If it was, then it would be so vague as to be meaningless.

Tone mapping is closely related to HDR and very often used, but is not necessary and does not define HDR. To me it seems like your argument is straw man. Photographers have never broadly used the term “high dynamic range” as a phrase, nor the acronym “HDR” before it showed up in computer apps like hdrView, Photoshop, and iPhone camera.

Oh, sorry, you're right. Mentioning the abbreviation is a red herring. The full quote is:

"But what if we don't need that tradeoff? What if I told you that analog photographers captured HDR as far back as 1857? Ansel Adams, one of the most revered photographers of the 20th century, was a master at capturing dramatic, high dynamic range scenes. It's even more incredible that this was done on paper, which has even less dynamic range than computer screens!"

It seems pretty clear to me that in this context the author is referring to the high dynamic range of the scenes that Adams pointed his camera at. That's why he says "captured HDR" and "high dynamic range scenes".

Yes, this is the problem I have with the article. “HDR” is not characterized solely by the range of the scene, and never was. It’s a term of art that refers to an increased range (and resolution) on the capture and storage side, and it’s referring to a workflow that involves/enables deferring exposure until display time. The author’s claim here is making the term “HDR” harder to understand, not easier, and it’s leaving out of the most important conceptual aspects. There are some important parallels between film and digital HDR, and there are some important differences. The differences are what make claiming that nineteenth century photographers were capturing HDR problematic and inaccurate.
