Hello Argiris,
the only thing I did was:
- croping away the small frame
- using Curves for better balance of colors and lightness
- using shadow/highlight for a well brightness balanced foreground
- after that the sky was too bright so I used a mask to correct the brightness of the sky
- selecting the sky (without clouds) and using surface blur for noise reduction (there was only some noise because of my editing)
- after using surace blur it was a bit unsharp so I used sharpen edges
- maing the new frame
- seting down image size
And if you followed the instruction you can see itīs no problem if sth. makes sh. else unsharp or so, you can always correct hat with an other tool.
Hope you like it,
Cheers! Kris
