Here is my long over due review of a wireless flash trigger system I have been using for the past year. I was lucky to get in touch with Jesse from Aputure (yes, Chinese brand), and I was given samples of the Aputure Trigmaster Plus 2.4G transceivers for my Canon system to review. They work exactly like my previous Pocketwizard Plus II system, each device can perform either as a transmitter or receiver. The purpose of a wireless trigger system is to use off-camera flash for either a more flattering, natural, or even dramatic lighting – basically anything but on-board camera flash! The system allows for 1 or more flash, in my case I use up to 3 flashes.
