Introduction to Lighting

Properties of Light
Hard Light/Soft Light
Light is made of rays that travel in straight lines.
Light is considered ‘hard’ when all the rays are pointed in the same direction and are parallel to one another.
Hard light creates shadows with very distinct edges and a hard transition between light and dark.
Light is considered ‘soft’ when the rays are less ordered and instead of travelling parallel to one another, they are at different angles.
Soft light creates gradual edges and a soft transition between light and dark.
Hard light can be ‘softened’ by reflecting the light off a surface or by using translucent materials to diffuse the light. Soft light can never be ‘hardened’.
