Yesterday im playing with cheap ebay wireless flash trigger 4 channel, take some picture of the student who learn chemistry in the school, well the idea is simple, Create ambience with color gel, attach to SB28 and 26 with remote, shoot the object with another SB28 with snoot in it.
But frankly speaking, i hate to use this ebay remote, its very unstable, sometimes it fire by it self, until i try to change the channel, and finally i change the channel to 1 and on (as you can see on the dip inside the remote). This configuration is the lowest noise/ interference i can get, yes still fire few times by it self but not as many as the other channel.
