Older, but no wiser

All that playing around with photoshopped pigeons and the like has payed some dividends; I wanted to do some work on this photo a while back, but hadn't figured out how. The sea and the sky needed different treatments - working on the photo as a whole, if you bring up the highlights on the sea, those in the sky got totally burned out. But using layers makes differing treatments possible, especially when there's such a convenient demarcation between land and sky.
