How To Do Ratio Lighting With Speedlights

In this video, I show how to use multiple speedlights to create ratio lighting.

Using a Canon 600EX/RT as the master, with a 580exII and a 430exII as slaves in exposure groups A and B, I explain how to setup the slaves to be members of different exposure groups, and how to program the Master controller to specify ratios. Also covered is synchro-flash techniques, showing how to shoot Manual mode to control ambient light in relation to the flash.
