Lighting

Seeing Light

On the light spectrum there is a small section of light that is visible to the human eye.
This section contains the colours known as Roy G. Biv or Red, Orange, Yellow, Green, Blue, Indigo and Violet.

The way we see colours is through reflected light
White reflects colours back
What we see is the light bouncing around off objects

There are two types of light
Hard Light
Soft Light

Positioning of lights
Different light positions are required under different circumstances such as skin tone, shape of face and even glasses
