This picture was taken with 2 different exposures. Both of them were taken with ND 0.9 to smooth the water. Adjustment was made by changing the profile to Lab color and I did some color tweaking a little bit. The rest was selective sharpening to bring out all the details in the clouds. I always fascinated with the cloudscape ^.^ I hope it helps a little bit.
Amazing depth and coloring. Umm...do you think you could put some details about how you took and postprocessed your shots? It would really help us that want to take pictures like that.
