Hmm, unfortunately I don’t have any good recommendations. I’ve just tinkered with it until stuff I like happens, and it’s been so long since I used Lightroom I can’t speak to specific differences.
With the contrast example it sounds like maybe the RT/DT tools are more literal, and Lightroom is more “smart” perhaps? I usually use the curves panel for this sort of thing, like if I want to bring down some highlights, I’ll find whereabouts they are on the histogram and target that area specifically. If I want a lower-contrast image in general I may compensate for some dullness with the local contrast and saturation tools, or if it’s the common scenario of a washed out sky, I’ll probably use a graduated filter to darken the sky without messing with the foreground.
I’m just guessing though, so I don’t know if this is helpful at all.
Well I’m glad that helps! I enjoy this stuff.
The histogram is neat, I used to just look for “lump in the middle = good exposure” but there are so many other way to make use of it.
There’s a panel that I think is present by default in RawTherapee, in the upper left corner, that shows a histogram, and when you hover your mouse over your photo, it has a sort of gauge across the bottom that marks where the pixel under your mouse is at. This can be helpful with determining which bit you want to target with adjustments.
There’s also a neat way I’ve found to get the most out of some images…in the curves panel, starting from the bottom/left/black, make the curve climb steeply where the histogram spikes, and then level off a bit (not totally level, but less steep) where the histogram dips. This seems to give more apparent contrast, without pushing the highlights or shadows too far apart. I hope that makes sense. It’ll take some trial and error but might give you something like what you were getting in Lightroom, with shadows and highlights both near “correct” exposure, but avoiding washed out and dull.
