One of the composition tricks in a photographer's aresenal should be the leading line. Something about the picture that draws you into the shot. A corner to peek round, a path that you want to follow.
Well, in that frame of mind, there are some pictures that just demand to be taken...
OK, so there was more to this than frame and click. I had to place the footpath through the new crop in the right part of the frame, and then I had to wait for the cloud to do exactly the right thing to the field below.
They say all things come to he that waits.
