If you are too afraid to clean your sensor (I know I was for MONTHS!), clone out the spots in pp work, that is what I (still need to) do... for while I got the "first spots" taken care of when I finally set out to clean my sensor, I got new ones now :roll:
But I must say that, yes, the second sure has "that certain something" that elevates it above the other two. Though the last is also QUITE QUITE detailed!!!
Presentation (to my mind) is not reaching its optimum, though, as the two blues (sky in 1 and sky in 2) don't like to be put one next to the other (well, that is my feeling here).
