I am not a big fan of over processed images and generally favour subtle tones and detail.
On this occasion thought the clouds were so intense and brooding that a dramatic representation was all I could think of.
At the same time I have just started experimenting with Silver Efex Pro in the Google Nik Collection.
Until I settle down with these new tools learn how to use them well, expect a little drama!
