When the moon is full, there's always something a little odd in the air. People and other animals seem to behave a little bit differently from the way they normally do. I'm not the first to observe this; I won't be the last.
One very interesting thing about night is that there are many things you don't see, even when you look right at them. But I think you can say the same about things you see in daylight.
In the dark, the rock at the head of the path is dappled with light and shadow. Put in another way, the light and shadow are distributed unevenly across its surface. You would not be able to predict, on the basis of a general understanding of what happens to an object in a dark environment where that object is illuminated from an angle, exactly which parts of the rock reflect light and which parts are in shadow. This confusing lighting situation is the result of multiple light sources and probably also the presence of one or more objects between these light sources and the rock which cast shadows onto its surface.
A grainier shot, but one that shows certain aspects of the scene that I may have missed in the shots in the previous posts. Documentation may require a variety of shots.
It can be hard to decide which is the definitive image of a given subject, even when one is making a selection from amongst images taken within a period of a few seconds. The multiplicity of images and the unresolved decision as to which should represent the subject may, in fact, be the subject.
