William - The sky in that shot disappeared into the smoke and I could barely make out any clouds although I knew they were there keeping the smoke in the valley. Sometimes the sky just isn't there, as in this shot taken during winter. After the long low clouds the sky disappears into the screen unless framed in black.
My favourite subject to photograph is clouds. I contribute to the Sandbox thread of 'Interesting Cloud Scenes' and I have posted a few shots there that I am very proud of. I have been trying to capture the skies that the artist J.M.W. Turner painted in the 1800s. They are on page 10 - Feb 21, page 12 - Mar 20 + Apr 1. I no longer have those shots so that thread is the only place they appear.
