JB, Thank you. I have a MS in EE and worked in the SW side (Computer Aided Design for Integrated Circuits).
So you are spot on as to my background.
As for the technique I did look at the link you posted previously
and I was looking at another youtube video for a different technique for landscapes and felt that technique
is equally applicable, if not more, in these pictures.
As for the adding MW to sky using Luminar 4, I am not sure yet. I may look at the SW for adding drama to
boring sky shots I have but with beautiful subjects. I have some Venice panoramas from San Giorgio Maggiore
that do have rather boring sky and may consider adding some drama just for the fun of it.
