An imaging control apparatus includes: a processor; and a radio communication unit capable of selecting a first transmission mode and a second transmission mode, the first transmission mode involving wireless data transmission to each of a plurality of imaging apparatuses with reception of a receipt acknowledgement from the imaging apparatuses, the second transmission mode involving simultaneous wireless data transmission to the imaging apparatuses without reception of the receipt acknowledgement from the imaging apparatuses. The processor performs a communication controlling step involving, in the case of instructing at least one simultaneous shooting process to the imaging apparatuses, separately transmitting each piece of shooting preparation instruction data instructing shooting preparation to each of the imaging apparatuses in the first transmission mode, and then simultaneously transmitting shooting instruction data to the imaging apparatuses in the second transmission mode.
