GIMP 2.10.6 out-of-range RGB values from .CR2 file

[Elle (Elle Stone)]

Returning to the topic of vocabulary and the word “HDR”, Mark Fairchild uses the word “HDR” when referring to images and scenes:

• In a talk given by Mark Fairchild (https://www.youtube.com/watch?v=fjt7VHarVu4&feature=youtu.be), in the fourth and fifth minutes Fairchild has a slide that has the words “HDR stimuli” and “LDR Stimuli”.

  In that same time frame he uses the phrase “high dynamic range images”.

  Earlier he talked about scenes with diffuse white, and then “extended range” scenes, so apparently Fairchild sees a reason to distinguish between images and scenes that are low dynamic range, ones that are only a bit past having a well-defined diffuse white, and ones that are high dynamic range scenes.

• See this page on Fairchild’s web pages at RIT:

  Welcome to the HDR Photographic Survey

  Quoting the intro sentence, “This page is the home of the High-Dynamic-Range (HDR) Photographic Survey, a unique database of HDR photographs”

  Rendering HDR images

There just isn’t any such thing as “HDR”[1] for example, which is at least a huge chunk as to why so many folks get confused about particular encodings.

We’ve looped over this dozens, if not hundreds of times. Keep with whatever you do.

[1] Save for the legitimate application of “HDR display”, which is a whole other kettle of fish.

@anon11264400

Note “HDRI” is an actual class of things, not to be confused with random idiot saying HDR. So yes, I should have included HDRIs, although the “I” in this case differs it from HDR. As I also said, HDR display is firmly acceptable, and refers to an entire class of displays.

@gez

Scene-referred images.
Implying that they are “HDR” means that there is an extension beyond a standard dynamic range

@anon11264400 - thanks! for posting that video link for Mark Fairchild’s talk over in this post:

Introducing a new color balance mode in darktable

This feature has been merged today in darktable master branch and will be released (as far as I understand) in dt 2.6, next Christmas.

I had watched that Fairchild video earlier this year and wanted to rewatch because there was a part in the middle that I didn’t understand. I was going to ask you about that part of the video. But in the meantime it seems you or someone deleted several of your posts to that “color balance” thread, anyway, I can’t find your post with the link to the video. But thanks much for posting it anyway.
