Ok so recently I got 3 wescott strobelite plus strobes. I posted in here that i was having problems fireing them off with my cheap RPS studio wireless triggers but then someone helped me and it resolved it. So now i have a new problem. In the studio i am using one reciever with a sync cord on one light and all 3 of my lights are going off which is great:thumbupObviously this is happening through the optical slave) So then i go on location and i power all 3 lights with a vagabond port power 2. None of the lights optical slave and i assume its because of the sunlight overpowering making it hard for my lights to pick up other flashes. So i run 2 transmitters on 2 different lights and they work great. One light still wont go off through the optical slave. I go up to it and its ready to fire i hit test it goes off... So i take my one transmitter and try it on the light that wouldnt fire and it isnt talking with the camera I get no flash out of it at all on location and it is always the one light that does this. But then when i go in the studio it works dandy... Sorry for the giant paragraph! any help is great! I am thinking of getting cybersyncs to try and see if that works... thanks!
