My normal workflow is geeqie rawtherapee gimp on linux. I’m on vacation now with no wifi, using Photoshop on mac laptop, which has"vibrance and clarity," which appear to be increasing saturation and contrast in the mid tones only.
Is there a way to do the same in raw therapy and/or gimp?
I’ll have to wait a month before I can try it…when back home with linux.
For controlling chromaticity, see:

For “clarity”, there’s a bunch of ways, the easiest would be using the new Local Contrast tool - available in current development builds and in the upcoming RawTherapee 5.4.

+1 to the local contrast tool, it works nicely!
In RT, you can use Contrast by Detail in the details tab or use wavelets’ details levels or like this:
Hi there,
part two of “enhancing local vs. global contrast” this time using RT and it’s unbelievably powerful wavelet tool.
We start with an image where all the basic settings have been done (exposure, sharpening, blablabla…)
[Basic-1]
We then activate the wavelets. In this example I set the wavelet levels to 9. Go to Residual Image pull down the contrast to you liking. I set it to:
[Res_image]
And the picture turns to this:
[Global Contrast]
Then go to the Final Touchup. Here activate t…
Or in Gimp you can do one of those:
Refined Unsharp Masking for Local Contrast
This tutorial is done in Gimp, but the basic ideas could be applied in any other layer based software (like photoflow, etc…)

Notice that all images shown in this tutroial, except the original image here, were resized for faster upload speed. The original is in it’s original size so that you can use it in case you want to try this yourself.

Here is a little techniques I have been using extensively lately to enhance local contrast vs. global contrast, using the great color to gray tool. It is fairly easy and fast.
Starting point, a picture with strong global contrast

Duplicate the layer and desaturate it (copy this also into your channles stack for easy acces as mask). Invert the desaturated layer and set it to overlay mode. this will minimize global contrast (and also local contrast). Here is the result setting…
