Think about light from anther way----artificial light and shadows

When I think about light and shadow,I will remember sunlight,windows,gap and so on.Those words exist in really light world.If some place do not have light or less light,how can I solve this issue?So think about light in anther way---artificial light and shadow.

The salon is a great example to explain artificial light and shadows.
