Boris @s7habo, since you supply us with so many excellent videos on using dt, I am wondering what you set your Luminance to when calibrating?
More generally, is there a typical level used by those who post images on the net? And what about printing? What do people find works best when they have photos printed?
How bright is your room… And keeping that consistent is also important… so not in the dark sometimes and with lights some times…
These conditions will influence what works best
I have an EIZO monitor that calibrates itself. This happens mostly at night. I have no other settings. As for processing photos, I make sure that the screen always has a medium gray background. Under this circumstance, the colors and brightness of the photos are always constant.
A very good control over this is provided in darktable by color assessment condition button.
As for printing photos, I do not do this at home. I use a photo store nearby that does a good job.
Thanks for the replies. What prompted my question was that I was re-watching Darktable Episode 75: Color harmonies part 4. At the very beginning of the processing of the first photo, before anything had been done, so it was at step 11 in the history, and comparing that to what the same photo looks like at that stage in my dt application, mine is much brighter and not as red.

I last calibrated my monitor, a BenQ, on Oct. 1. I would like to figure out the reason for the differences. I assume your monitor is calibrated to sRGB, and you use Linear Rec2020 RGB for your input profile.
???
Oops. Working profile. Input color profile: standard color matrix.
If you have repeated the steps from the video exactly, it can’t be the screen. Then there are more likely to be differences in the settings in darktable.
Which can also play a role, I use the developer version of darktable for videos.
And I have not changed the internal working color profile. It is still Rec2020 RGB.
Maybe lens correction on vs off … just a guess from looking at the corners??
I use the nightly builds. Both screen shots were taken at step 11, the end of the standard steps applied before any modifications are done. I think it must come from my calibration. That was why asked about the Luminance setting. Other than the settings I have already mentioned, I don’t know what other setting in dt would affect the image.
Here is my screenshot from Boris’s video I will see if I can find the image… just wondering if screenshots can simply vary or some gamma or other slight tweak that happens when making and rendering the video… I guess I am not sure that you can compare a screenshot from a YT video and what you see processes on your screen and get direct answer as to why they are different…
EDIT… I scrolled the entire signature edits site and couldn’t find that image so I might have missed it or maybe they rotate out photos??
EDIT2…
This is mostly about video but but as you can see there can be nuances around software, OS settings and video card driver settings… I think actually the NVIDIA might default to the reduced DNR… I have mine just set on defaults right now so the OS decides. I feel like I used to have it set to full and used the nvidia driver… Things you discover poking around in any case… there can be nuance to these things that might not be a simple luminance calibration difference…

It seems they do rotate out photos, but some images from Boris’ earliest videos are still there. Go figure.
I was also wondering as to me it seems like the edges are really the difference… could you be using one lens correction method and Boris maybe the older lens fun… again it might not be a lens correction thing I was just trying to compare but the number of little things that could impact is with a screenshot can obscure things… if you could get @s7habo to send you an exported jpg taken at step 11 you could compare there an then maybe decide if there is still such a difference??
That would eliminate the browser and YouTube effects.
