Wind in the Barley

Misty day today.
Rain has generally held off, but near the coast everything grey and misty.
However, was quite bright so headed off later on to see what the day was like elsewhere with no mist.
Colour was still surprisingly flat but clouds had potential.
So a quick snap and then a play this evening with black and white.
I need to start experimenting with things other than CS5 raw editor to see what I can achieve.
Anyone any suggestions as to plugins or programs for colour or black and white processing.
