Wikipedia entry: https://en.wikipedia.org/wiki/Camille_Claudel
When looking at sculpture, as well as when sculpting, close your eyes (squint) to see the large and small areas of light and dark as well as the masses of form in space. The key to sculpting from life is being able to see the large connections and masses in their simplicity and organizing their complexity within a larger rhythm and form. Repetition, variety, large and small lights and darks are key. Each sculptor will have a different way of handling light and dark. When you are sculpting you are always looking at the direction of light and by turning the clay, in varying degrees, away from the light, you change the intensity of the values from darkest darks, to lightest lights.

In the photo below is Camille Claudel working on a large figure in clay, notice how she has the landmarks of the ear, top of head and elbow marked with a stick to keep track of it and keep the modeling of the head in line with its bent orientation.
