Paper Abstract

This paper deals with the variables encountered in lighting for high speed photography. They are film exposure index, F stops, exposure time, target size and distance and frame rates. An understanding of the inter-relationships of these elements permits calculation of required lighting intensities from continuous duty tungsten halogen lighting equipment for an effective result. Selection of the appropriate lighting equipment for the lighting is discussed based on light source efficiencies, throw distances, and intensity requirements. Effects on exposure due to extension tubes or bellows are discussed. Eastman Kodak's introduction of high speed video news film has opened a new opportunity in the enhancement of data acquisition due to its high exposure index and as a result reduced lighting intensity requirements. Types of lighting equipment and their characteristics are discussed along with the basis for the selection of lighting equipment for particular high speed lighting tasks.
