I was going to say that the moment I saw Frans' question, I knew there would be a snarky response from you.
And you were correct sir. Because we have
years of history here and on PhotoNet where Franz asks a technical question with (usually) the incorrect answer predetermined in his head, then pushes back when the technically correct answer is provided.
Do you require a paper trail of such proof? I have it all archived for copy and paste.
Now what I did do is partially answer his question which thus far, no one else has attempted. You are all free to answer it in a technically correct fashion or by just guessing like Franz.
Franz is guessing indeed. But he's sure his guess is correct. And when someone here actually attempts to answer the technical question that doesn't fit the his predetermined answer, they too will get push back.
Do examine my admittedly partial answers in post #2 where thus far, the discussion is actually on topic with "
Consider".
The Histogram in ACR and LR isn't providing anything about the underlying data and depending on if ACR is editing a raw or a rendered image, the differences can be profound.
The Histogram in ACR and LR isn't just showing the clipping of Luminance! Or what some could call brightness of the image being previewed.
The Histogram in ACR and LR and numbers is showing us workflow options/Melissa RGB in most cases (there are ways of alter this in LR and I'm sure you and Peano are well aware of this of course
)
The assumption clipping therefore "
shows up at around a value of 250 and then moves gradually to the maximum value of 255" is a big fat guess. That answer was provided before two others came here to dismiss the technicality of the questions or answers.
So Slobodan, you've ventured into the topic, do tell us your understanding of the Histogram, RGB values and clipping in ACR and LR. The actual topic at hand. The floor is also yours.
