Quote: Illumination Theory
In order to fully appreciate the findings of this project a basic understanding of illumination theory is desirable, as set out below. This section is based on Ryer (1998) and Scieber (2000). Light is visible electromagnetic radiation and covers wavelengths from 380 (violet) to 730 (red) nanometres. The
human eye is more sensitive to the middle wavelengths (green and yellow) and perceives these colours
as being brighter for the same radiant energy. To account for this the measurement of light (known as photometry) involves the application of a bell-shaped weighting formula to the radiant energy. The weighting system was developed by Commission Internationale de l'Eclairage (CIE) and is known as
the spectral luminosity function.
