Abstract
Photography has become accepted as an important tool for the scientific worker. The student or the new research worker, however, aften finds difficulty in utilising its full potential because of his limited knowledge of the photographic process and of the methods of applying it to his particular problem. Since the capital outlay for equipment and running costs can constitute a large proportion of a limited research budget, it is very necessary that both the scope and limitations of the available methods should be better understood.
Problems in application and the higher running costs are usually associated with photography when applied to the study of movement. In this note an attempt is made ta classify the wide variety of techniques which may be used in the study of movement and illustrate how the choice of method must be related to both the type of phenomena studied and the type of information required.
