Fire In The Sky

The sky was amazing last week. I shot these photos and left them unprocessed,(except for the odd sharpen). I wonder if it is the clean air or perhaps the lack of ozone that creates such an amazing sky here in Tasmania. If you look closely in some of the photos posted it almost looks as if there is a fire on the hills. It is a reflection of the sun on a thunderhead rising up from behind the hill. What a display.
