I find the Raw Histogram in RawTherapee difficult to read, or perhaps I simply do not understand it despite having researched it a bit. What are its vertical and horizontal units and range when in log-log mode? Do they make sense?
One of the main uses of a Raw Histogram (at least for me) is to check how many pixels, if any, are blocked/clipped. In the image below, it is obvious from the second and third histograms from left (RawDigger and FastrRawViewer resp.) that there is an inconsequential 1/3 stop headroom and a few blocked blue pixels. Good, that’s all I needed to know.
Why can’t I see that in RT’s raw histogram (first from left)? Am I not setting it up properly?
PS Reserve question: would it be possible to have clipped/blocked stats displayed, perhaps only after pressing a button?
