I was out before sunrise but it was a misty morning and the sunrise was not visible so I spent some time taking close-up shots of rocks in the mist. As I walked back up the beach the mist started to clear and this rainbow, or fogbow; as white rainbows are known, appeared. I was fortunate that my 10mm lens was wide enough to capture both ends.
This is the rainbow/fogbow mentioned in my previous post.
