Any scene you look at is nothing more than a series of shapes essentially created by tone and contrast. This is why,artists start work on a painting, they begin with a very rough outline of what they can see, and then block in shapes in light and dark tones to give their image a structure to add the detail to. We photographers can’t work in exactly the same way, but we can visualise the structure of a given scene by squinting slightly to remove the detail and consider the balance of objects.
