Before I got Photoshopp CC I oly used Camera RAW for pre processing. However, the ability to call up ACR during post processing is a huge advantage - especially as I can apply it to selected parts of my images. The most used operations are (a) change color temperature and (b) haze reduction. Both were used in for the images here. N.B. I usually feather my selection before tweaking anything.
There is flare in #2; I hope my attempts to reduce it are not too obvious
