Abstract: A photographing method in which a terminal device performs photographing is provided. The photographing method includes synchronizing a clock of the terminal device with a reference clock, and acquiring photographing clock time information indicating a photographing clock time which is based on the reference clock through a communication network. The photographing method also includes specifying a photographing delay time until the photographing is performed since photographing start in the terminal device, and photographing a subject at the photographing clock time indicated by the photographing clock time information. The photographing clock time being based on the clock of the terminal device already synchronized with the reference clock.
