Hello,

dpreview wrote news about a new ACR version and it's HDR support: https://www.dpreview.com/articles/7584045384/adobe-demos-true-hdr-support-in-adobe-camera-raw-giving-a-glimpse-of-photography-s-bright-future

I read more about it, especially from Greg Benz's blog. He has a test page here to see if your HDR setup works: https://gregbenzphotography.com/hdr/

And a tutorial video about setting up HDR in Photoshop & ACR:

(he has a few more videos there too).

So I have the following setup:

LG C2 42" OLED
Windows 11 22H2
Google Chrome browser

And editing seems to work fine. As dpreview mentioned, color grading doesn't quite work. I also get some blue in some highlights and can't figure out why. I haven't used ACR much so it was kind of pain to edit photos with it. Hopefully Lightroom gets HDR REC.2020 edit support soon.

I also posted a few examples here. SDR images are from old Lightroom edits, I tried to do a similar looking HDR edit in ACR for comparison: https://hakkarainen.kuvat.fi/HDR/

If your setup doesn't properly support HDR, or you use a browser which doesn't support HDR REC.2020 AVIF files properly, the results don't look good. Vivaldi and Edge didn't seem to work, didn't try out Firefox.

Has anyone else tested HDR editing? I'm interested in seeing what other people can do with this new tech in still photography

yes I did a bit of testing, on a macbook pro which has a mini led screen. Looks really cool. As mentioned, the options are still a bit limited. And I wish more export options (heif/heic?) would be available.

I tried to import a couple edits in avif format into final cut in order to create a hdr slideshow in rec 2020 with it, but no luck yet. However, I can see the potential of this!

I understand why browsers aren't very keen to support HEVC encoding Apple uses. The licence is apparently $2 so you'd have to pay $2 for every Chrome installation for example, times the amount of browser installations, 2 billion dollars or something? Not going to happen.

HEIF supports other compression methods too, like AV1 which is a free and open format, so it's a LOT easier for software developers to support it. That's why browsers support it, Adobe supports it etc.

So AV1 compressed HEIF (== AVIF) is probably the way to go in future because of licensing costs. Adobe also recently broaneded the HDR support, now Lightroom supports HDR too in addition to ACR, and you can even enable HDR editing by default!

I also learned that Lightroom can export gainmapped JPG files as HDR.

This means that people without HDR capabilities will see them as regular SDR. With full hdr setup, it should be visible as HDR. So the same file holds both SDR and HDR versions, which is very handy:
https://helpx.adobe.com/camera-raw/using/gain-map.html

Greg Benz wrote more about it: https://gregbenzphotography.com/hdr-images/jpg-hdr-gain-maps-in-adobe-camera-raw/

This way you can use an already supported format (JPG), and the HDR is only in the file's metadata.

I uploaded an example file here. It should display as an HDR image if your software supports HDR. Otherwise it should be displayed in SDR. https://hakkarainen.kuvat.fi/kuvat/2023/00+-+HDR-testikuvia/gainmap/_1063744_3840px-HDR-gainmap.jpg

It can also be downloaded and opened in the Adobe Gainmap demo tool. You can switch between SDR and HDR modes, or view only the gainmap. Very nice. I'll probably export images as gainmapped HDR JPG's in future. It seems to be the most compatible format available right now.

In that Adobe blog, Eric Chan writes:

"In HDR mode, the Point Curve is divided into two parts, SDR (bottom and left) and HDR (right and top). The HDR section provides direct and very precise control over the highlights..."/I]

Well, that's nothing new. The Point Curve has been, and I guess still is, one of the main highlight controls. But basically it mutes the bright whites without adding contrast.

I tried the HDR module with black & white image highlights and was left wanting.

I'm an eternal optimist so hopefully a trick will be revealed.
