The Physics of Light: Starting on the Right Wavelength
Light is a particular range of electromagnetic radiation that stimulates the optic receptors in the eye and makes it possible to determine the color and form of our surroundings.
Light has three properties that contribute to our perception of the things it illuminates:
• color • quality • intensity
Lighting directors must have a basic understanding of all three properties, from a scientific point of view, to make an artistic contribution to the productions they are lighting. In Chapter 1, we will deal with the aspects of color and quality; in Chapter 3, we will discuss the quality of light provided by various lamp and reflector types; and in Chapter 4, we will discuss aspects of intensity.
