This is a very incomplete answer, but important in regards to terminology and understanding everything: RGB and CMYK are color models. They don't define what your monitor or printer can do, only how color is created. A great question to review: What is the difference or relation between a Color Model and a Color Space? He also told me CMYK is a 100% ...


In my opinion the designer is wrong. CMYK is NOT a subset of sRGB. It is a diferent color model. Let me explain. sRGB is a color profile for rgb colors. But actually it is close to a "color space" (yes, this afirmation will be controversial). On top of that you "profile" your monitor and computer conected together. But there are tons of diferent ...


That Adobe seems to butcher the colors of all my raws drives me nuts You are wrong here. What you see on the back of your camera is not the raw file, but the JPEG preview, which includes whatever setting you dial in your camera. That includes contrast and boost of saturation. LR cannot reproduce the same look from the raw file, because the process is ...


Part of this question basically seems to be asking if the answers to the other question are actually right. For that part, don't worry — they are. (And no information is lost in this way — the leader of your course is wrong. *) The other parts of the question basically ask if (and why) this information is stored at all, if it doesn't affect the raw data. ...


One thing I don't fully understand is why, when I take a photo with a Nikon and import it in Lightroom, the colors immediately appear desaturated and visibly different than what it looked like in the camera. This is just a different interpretation of the raw data. Lightroom can't read the preset information from Nikon files, it seems and applies some sort ...


RGB and CMYK are very different color models. For instance, RGB is additive: you basically start with black and add colors. You combine all colors to make white. But CMYK is subtractive: you start with white and add colors to generate black. If you think about it, it makes sense: Monitors are black by default, when there is no light, the screen is black. ...


You are not clipping the intermediate RGB values. From the sRGB Wikipedia article you linked to, The intermediate parameters R, G and B for in-gamut colors are defined to be in the range [0,1], ... The linear RGB values are usually clipped to that range, with display white represented as (1,1,1) From the W3C sRGB spec you linked to, ... XYZ are ...


There seems to be a good analysis of the issue here:


I believe our eyes have this response curve, but this response to a sudden change in the amount of light, especially if it got higher but in the same time the brain decodes that response by narrowing our iris to maintain the same (linear perception) we have while in a stable viewing condition until transition to the new viewing condition happens smoothly. ...
