1. A method for controlling one or more remote photographic flash devices from a camera body, the method comprising:
- electrically receiving a flash synchronization signal internal to the camera body;
using the flash synchronization signal to generate within the camera body an RF signal;
communicating the RF signal via a wired connection to an antenna external to the camera body, wherein said communicating of the RF signal via a wired connection includes communicating the RF signal to a port having an external connector on the camera body to which the antenna is connected, the external connector being a PC flash synchronization connector; and
wirelessly communicating the RF signal from the external antenna to the one or more remote photographic flash devices.

Abstract
A system and method for controlling one or more remote photographic flash devices from a camera body. Wireless functionality within a camera body provides wireless communication of a signal from within the camera body to one or more remote devices. In one example, a flash synchronization signal of the camera body may be wirelessly communicated using a wireless communication functionality within the camera body and an external antenna to one or more remote flash devices for triggering the one or more remote flash devices.
