Thanks for all your kind commends and suggestions. I'm afraid the particular frame I converted to B&W really has no clouds in it. Might try another frame, though there might be different issues, that is: wind ... as color is mentioned: True, there're rather saturated. Probably after the winter I was helping spring a bit too much, color-wise. Actually I think I really need to go there in a week or two, when the leaves really show. Thanks again!
