While working on color critical tasks, what do you do to avoid your human vision system drifting into a too uncanny calibration state?

Some pictures on screen? Something to look at outside the screen? How do you choose what to look at?

@troy_s @petrikas Interesting!

What makes a good bias light and what it illuminates? Is it a constant or should it be changed based on the task?

How about an on-screen border area as the bias light, with a black gap to the worked material?

@tmw Thanks! Their pdf on setting up a viewing environment is nice too.

it is beyond frustrating how much damage / misinformation the anti-systemd/anti-wayland/anti-woke Linux weirdos have spread throughout the years

@dysfun What things do you see having zero relevance to desktop?

@dysfun Sorry, I thought you had some tangible features in mind where people have spent effort, but do not benefit also the desktop. E.g. some protocol extension. I cannot think of a single protocol that isn't somehow relevant for some desktop.

@dysfun I think the protocol modularity is good for the desktop in the long run. Problems and use cases can be solved one at a time, and they can be iterated on. Solving everything at once would take even longer, or the result would be just another copy of what already exists without any clear way to try something new.

It is somewhat curious that all unit metrics are dependent upon at least one secondary implicit dimension that is rarely, if ever, stated.

@Ronflaix
Where do you find W/h? Acceleration of energy transfer or consumption - joules/s^2.

Or do you mean Wh/h, amount of energy consumed in an hour - average joules/s?

Have linux youtubers ever brought attention to a problem in a way that actually helped solving it? Preferably without burning people in doing so?

@BrodieOnLinux FWIW I firmly believe that snarkyness, sarcasm, and ridicule will only cause unnecessary negativity. They rally people to have "fun" by punching down the target. They are powerful tools of destruction, that create a mob.

Luckily I haven't read posts that target me in a long time, but I can assure you, the emotions the comments trigger in me are hatred, sadness, frustration and demotivation.

@jon_valdes @demofox I wonder what data types you/they used there and for what kind of data, to cause all that need for dithering? Optical vs. electrical, primaries, dynamic range...

@pq@floss.social avatar

@jon_valdes Oh, don't worry. I always wonder if there is some insight I haven't realized yet.

I have indeed been doubting if 10 bpc is even enough for electrical BT.2100/PQ, and I've been hoping that 16-bit floating-point would be enough for optical display-referred data.

@jon_valdes

Very long and slow gradients is a good point to make. Without dithering we would need the stimulus change from one code value to the next to be imperceptible when laid out as two flat fields side-by-side.
