We're excited to announce that Radiopopper has decided to become a sponsor of the 2012 UPAA Symposium. RadioPopper makes wireless flash control systems that allow you to have ETTL control of your flashes wirelessly, without line of sight. Our own Mark Carriveau recently did a review of the RadioPoppers in the Contact Sheet.
For the Symposium they will be providing loaner units to test out during David Tejada's lighting workshops. They have also provided a $250 door prize so that one lucky member will be able to pick up one of their flash systems. Check out their products at:
