#2 has a more contemporary look to it, which I presume is from an orange or red filter, making the blue sky darker.
The first is more authentic, if that's the right term, especially as to the luminosity of things in that scene, BUT... I'm wondering if you used a blue filter there to bring out the darker detail of the uprights?
I prefer the second image, like Doug. To me there is more strength to the image, with the darkened down sky making the uprights have more detail, or rather having them be more brought to life with the darker surround, after all, the eye is a huge sucker for contrast.
Now I'm wondering, is there a filter applied to both? One in the reddish spectrum and one in the blueish spectrum?
Feedback and honest, constructive criticism is greatly appreciated.
