“No shit, the world is wrong! It ain’t got a clue! But here, in this one minute video, I will explain what’s wrong and how I have discovered the right way.”
As soon as you encounter something that can be reduced to the above, it’s a pretty fair sign that the author doesn’t know what he’s talking about. Anyone who thinks they’re so unique that they can come up with something nobody else has thought before is, with likelihood bordering on certainty deluded. The world is full of smart people who have encountered the problem before. Any problem.
That means that a video that’s been doing the rounds on how “Computer Color is Broken” is a case in point. The author brings us his amazing discovery that linear rgb is better than non-linear, except that everyone who’s been working on computer graphics has known all of that, for ages. It’s textbook stuff. It’s not amazing, it’s just the way maths work. The same with the guy who some years ago proved that all graphics applications scale the WRONG way! “And how much did you pay for your expensive graphics software?”, he asked. “Eh? You sucker, you got suckered”, he effectively said, “but fortunately, here’s me to put you right!” It’s even the same thing, actually.
Whether it’s about color, graphics, or finding the Final Synthesis between Aristotle and Plato, this is my rule of thumb: people who think everone else in the world is wrong, are certainly wrong. (Also, Basque really is not the mother of all languages.)
And when it comes to color blending or image scaling: with Krita you got the choice. Use 16 bit rgb with a linear color profile, and you won’t see the artefacts, or don’t use it, and get the artefacts you probably were already used to, and were counting on for the effect you’re trying to achieve. We’ve had support for that for a decade now.
Note: I won’t link to any of these kookisms. They get enough attention already.
