Camera profile affect also Detail parameters, like Noise Reduction

[Enrique5E49]

I am new to Lightroom. I have a Nikon Z7, and changed the preferences to use Camera Settings profiles rather than Adobe Default. It renders better the colors as I want them. In particular the sky.

I noticed that a side effect, is that now LR automatically asigns Detail parameters to each photo (Sharepening and Noise Reduction). Was not the case with Adobe Color profile.

I am not necessarely against that, but want to understand more how these settings are decided (they are not the same for each picture). Actually, not even clear to me what each of these 10 parameters are. I have seen many "how to" videos, but no clear help that tells me exactly what each parameter is.

Thanks for your help

The Nikon Z series cameras actually include Lightroom/camera raw settings in the raw files. They typically affect detail settings. If you select camera settings, Lightroom uses these to change the Lightroom settings. So they are coming from your camera. Most of these settings are automatically determined in camera by some intelligence based on what exposure settings you used and scene recognition. You can see these settings if you open the NEF files in a text editor. Here for example is what was included in a recent shot on my Z7:

Thank you very much, Jao. This is exactly what I wanted to know. Remains to know how my camera decides, but this is a different story...
