We dropped in at Mottisfont Abbey, Hampshire, last Thursday to see an exhibition of photographs by Lichfiled, Donovan and Duffy. (It's on til 4 November this year if you want to see it: well worth the trouble!)
I darkened the sky separately to simulate a yellow or orange filter, and used a Black & White and Brightness/Contrast adjustments to get the selective contrast I wanted, after getting the verticals parallel with the Perspective tool.

(The chap on the bench is a scarecrow effigy of the artist Rex Whstler, who did some fantastic trompe l'oeuil painting here.)
