I use normal contrast if I want it to affect the whole image.
Local contrast - if I want to target more specific areas. For example - the smoother areas to remain smooth but the one with bigger color change to have some contrast. For the equalizer - a good start is the presets - for example - build in preset for clarity. Or build in preset for sharpness or denoise etc.

The manual is indeed very specific to explain how equalizer works - in particular the sample pictures.

You may want to check also this video - it is done by Robert Hutton

Equalizer is a very powerful module but it does take time to get used to it. I am at a level to use the presets and apply them with different scale.

https://dtstyle.net/ has a "skin retouch" style that uses equalizer. I find it very well done. It also shows some functions that I wouldn't have expected.

I recall looking at video (or reading something) comparing equalizer to wavelets plugin in Gimp but I was unable to find it now.

Hope this helps,

Please read the manual.
I did:

Much more versatility for contrast and brightness adjustment is
offered by the tone curve, levels, and zone system modules


Likewise you may adjust color saturation in a more detailed way with
the tone curve, color contrast, and color zones modules


This slider adjusts the image's contrast.

This slider adjusts the image's brightness.

This slider adjusts the color saturation.

Is there some table that compares the various multiple ways of doing
the same thing in DT?
