Occasionally I switch my camera to selective colour mode and here at the Hurst Point Lighthouse on a windy day, the sky was particularly co-operative with a variety of blue light and shade, though I did have to adjust the exposure a little as the intermittent overcastness always seems to happen just as I click the shutter (hence the grainyness).
Did you know that Pharology is the study of lighthouses? [from the Greek for light and the famous lighthouse of Alexandria] I just discovered this but am evidently in the mode as had just posted a photo essay on Orford Ness lighthouse when the lens artists photo challenge summoned up some Blue – and besides Monday in the blogosphere often has the blues.
