Learning objectives

To illustrate the additive color process.
To analyse our perception of color.
To cover a little of the history of photography, one of humanity’s great inventions.

Since the 1890s, additive color processes have been used to create color photographs. The cones that carpet our retinas are only sensitive to the primary colors: Green, Red and Blue. Television, cinema and photography all use these additive, three color processes, as did the pointillist painters of the 19th Century.
