DPP Solutions: Radio Triggers

On-camera flash will only go so far




Modern on-camera flashes are extremely portable and powerful, and their ease of use and relative affordability make them an ideal solution for working in difficult settings. The problem with these flashes is that most proprietary models fall into two categories, infrared or pop-up. Both can be extremely limiting when working with long distances and situations where your lighting source is out of the line of sight of the master flash. For maximum versatility, radio transmitters and receivers can circumvent the line-of-sight problem because the unique properties of radio waves allow them to penetrate most solid substances while also traveling great distances. The last thing you want to discover after setting up a complicated shot is that some of your strobes aren’t triggering reliably, and these wireless triggers are built to pop strobes and flashes with a great deal of control.

The MicroSync Digital transmitter provides four different channels to select from for working around possible interference. It fits to the hot-shoe, and its diminutive size keeps it from weighing down your camera. Receivers can be plugged directly into strobes or monolights, and off-camera flashes with PC sync terminals are also compatible with the optional sub-mini to PC sync cord. It works through walls at distances of up to 100 feet and syncs at shutter speeds of up to 1/180 sec. Estimated Street Price: $49 (transmitter); $69 (receiver).

Compatible with any PocketWizard radio transmitter, the PowerST4 receiver provides remote control of Elinchrom RX flashes, including adjustment of power settings from the camera position in up to 20 ControlTL channels. When used with the AC3 ZoneController for Canon or Nikon cameras, the PowerST4 will work with three zones of lights at 1/3-stop increments in up to a six-stop range. PocketWizard makes a variety of other wireless transmitters and receivers that are compatible with Canon and Nikon, as well. Estimated Street Price: $129 (PowerST4 receiver); $79 (AC3 ZoneController).
