Hi,
Thank you for your answers - I really appreciate it,
now I understand that my example is hard because it involved sharpening, which have to be watched in 1:1 - 0k.
To make things simpler - as you suggested - here is my example picture - suppose I want to sharpen the center, or only the upper half.
I understand, that I cannot just sharpen the entire elipse - I have to select tree, grass, and background (3 spots) each time and provide sharpening for this 3 spots ? Don’t get me wrong - I appreciate this “smart selection” algorithm, and I see many applications for me -e.g. sky. But I also want/expected straight “just perform changes in the entire elipse”. First time user of local changes (me) expect this as a first choice, and then whan you know how it performs - that advanced smart selection algorithms 
Or maybe there is such an option I haven’t found yet.
regards
