CRAP! Hey sorry about this
FHORNLEGHORN !
I srewed up here. DOH! [doh] I saw 2 photos exactly the same so went to remove one of them... and for some odd reason the board removed both.
Sorry about that. Please reattach your sample photo ok? Just click on the edit button at the top-right side of your post and go through the attachment procedure again.
Gee... what a great welcome this is huh?!
Really sorry. Welcome to the community though, hope you enjoy your stay!
To answer you question anyway, since i did see the photo...
First off, the photo was most likely taken with a very good camera. Some special lighting effects have been applied to the buildings and surrounding landscape it appears...
Plus, the sky is completely composited. It doesn't look to be the original sky... why do i say that? Look at the water... the clouds are not being reflected.
These combination of things, albeit not completely "filtered" as you were thinking, produce the overall finished effect/look of the scene.
That's my take. [excited]
