light and shadow

A light source can be natural (eg. sun) or artificial (eg. light fitting)

When the light changes, the shadows will also change in density (darkness) and shape. These need to be taken into account when designing an environment

When you look at the images of the copper nails, they change 'shape' depending on where the light source is and what shapes the shadows create.

The Italian for light and dark is Chiaroscuro. This was explored during the Renaissance period. Look at wood cuts, lighting, and painting to see the effects.

When light is shone on an object, shadows are created on the other side of the object. The brightness of the light, the type of surface and material of the object and the position will all affect how the shadows are formed. All these things should be considered when placing objects and light sources in an environment.
