Drew, good subject for B&W. However, with blue sky, you'll usually get a more dramatic result if you use a red channel mono conversion to give you a much darker sky, although it changes the rest of the image as well, which may or may not work for you. I've created a comparison here bwetween your colour version, your B&W version and my red channel mono conversion:http://www.pbase.com/image/46925614 Cheers, John
