A control system for use with preconfigured photographic equipment that includes a controllable photographic device controlled by a controlling photographic device is disclosed. The controllable photographic device has a housing, and a device circuit having an upstream portion and a downstream portion coupled by control lines within the housing. An internal module may be located within the housing and includes a signal detecting arrangement configured to be coupled with the control lines between the upstream and downstream portions. The system may also include an external module configured to be located outside of the housing, and coupled with the internal module. The external module may include a signal receiving device capable of receiving a wireless control signal from the controlling photographic device, and to cause a module generated signal to be sent by the internal module to the downstream portion upon receipt of the wireless control signal.
