Abstract
Aspects of the physical nature of light are reviewed as they relate to photography, including ray, wave, and particle perspectives. The formation of images by the geometry of pinholes is compared to the images produced by lenses. We describe the properties of incandescent lighting, sunlight, and LED lamps as they relate to the particular photographic processes described in the book. The physical concept of energy is related to the meaning of photographic exposure as the product of illuminance and time. The meaning of color is briefly surveyed in relation to human perception, selective absorption, and the wavelength response of photographic light detectors.
