Idea of capturing the time of a stranger being about to do something in monochrome was a kind of core themes for me but I have forgotten it for a long while.
A few weeks ago, I was at an old town and looking down a sea from one of windows at the ramparts. It was a peculiar experience. Everybody looks happy and everything is shining but what I was at was used as a lookout post hundreds years ago and it faced difficulties again a quoter century ago. The picture was not taken for the challenge but I chose this one.
