Hi-Tech Studio: Triggering The Light
Wireless flash systems give more freedom when it comes to creative lighting

The Sony HVL-F58AM flash unit incorporates Wireless Ratio Control to control up to three groups of flashes and specify the luminosity ratio for each of the three groups, providing multiple-flash lighting schemes. Also of note, the Sigma Electronic Flash EF-530 DG SUPER has a Designated Slave function, which lets you use two or more EF-530 DG SUPER flash units.
The main advantage to radio triggers is the range at which you can move wirelessly and trigger groups of strobes and flashes. The PocketWizard MultiMAX Transceiver can be triggered from 1,600 feet between transceivers. While you may not need that kind of range, it shows the capability of radio signals. Other benefits of the MultiMAX are multi-channel switching for controlling different lights, a sustained 12 fps high-speed-triggering ability and Selective Quad Triggering that lets you control firing sequences of various strobes no matter the brand.

MicroSync Digital is a very compact system that uses radio signals to synchronize groups of flash units or power packs. Link the transmitter to your camera’s hot-shoe and the receiver to your power packs up to a distance of 100 feet.
Quantum’s FreeXWire System utilizes eight different radio channels and gives you four zones of control, allowing you to selectively control four different sets of lights. Another great feature for Quantum Qflash 5D users—you can get wireless TTL control with the system. The FreeXWire transmits your camera’s ƒ-stop, ISO and TTL exposure information to the Quantum flash to make adjustments. The FreeXWire has an impressive range of up to 1,000 feet.
