It is the same in the social sciences, recordings facilitate the study of phenomena that are too fast, or too slow, or too infrequent or too big or too small to study directly "in the life." Most importantly, through editing visual sociologists can juxtapose events to produce meanings. Sociologists may also be able to put cameras in places where one would not put a researcher: where it is dangerous, or where a person would be unwelcome, or simply to remove the observer effect from particular situations, e.g., studying social behavior among school children on a playground.
