You can't imagine what you are missing!

This is primarily directed at those forumers that stubbornly refuse to
Read The Manual.

Background: Some time ago, I decided to switch to darktable,
to see what it could offer. Quite a lot, actually. And dt sure has
some very powerful evangelists as well as a bunch of skilled
tutorial writers presenting its benefits.

When RawTherapee 5.9 appeared, I wanted to catch up — and
I rapidly found out that I could develop an image faster using RT
than I could using dt.

I started to read Rawpedia, from the first paragraph to the last.
That was a time very well spent. Rawpedia contains a wealth of information
about RawTherapee — you just have to read, think and try
the built-in-tutorials for yourself. (Yes, you can even download the RAW files
used in the examples.)

Just to give a small hint on what you will find in Rawpedia:
Use Local Adjustments/Log encoding to do what dt’s filmic module does.

Have fun!

That’s one way to do it. In general, I’ve found that the Tone Curve module meets my needs 90%+ of the time for dynamic range management, and combining it with Dynamic Range Compression meets my needs 98%+ of the time.

I’ve found that sometimes using the Tone Curve module with the first curve in the default “standard film curve”, with a simple curve for the “second” tone curve (just raising midtones with a single spline knot) works well.

In general, the Tone Curve module maps most directly to “basecurve” applied late in the pipeline for the curve behavior itself, and “sigmoid” as far as color preservation if you use the default “Film-Like” setting - in fact sigmoidal’s hue preservation mechanisms were heavily inspired by RT’s “film-like” setting with a few additional tweaks.
