When I try to adjust the exposure of an Image I usually try out different exposure compensation values and then use the highlight clipping indicator to judge whether something important is overexposed. This process is a bit tedious and slow, as one has to repeatedly try out different values.
To speed this up, I had the following Idea:
Lets say I point the mouse to a certain part of the histogram. RawTherapee could then highlight image areas which contain colours in that part of the histogram (or alternatively, colours above that point or below that point, by using ctrl or shift or alt or so). This way, by moving around the mouse in the histogram, I could quickly identify which parts of the Histogram I’m willing to clip. A single click into the histogram in this position could then change the exposure such that where I clicked is then the new clipping point.
