Hi, I have recently brought an interfit infra red trigger. The intention was to use it to trigger my 4 lights and create that studio high key look. Trouble is it hasn't worked! It was very temperamental-at times triggering one, then none, then very very occasionally actually doing what I wanted it to and triggering all 4! Very frustrating! Has anyone else had this problem? Am I doing something wrong? Please help. FifiD:bang:
