Having some YN-622 issues and hope someone knows more about them and can help. Me and another photographer each have a 622 transceiver on our cameras with a flash on top of them for key light. And the transceivers are triggering 2 off camera flashes on stands with 622's under them. Issue is when each of us take a picture, it is triggering the others on camera flash as well. Is there a work around so that doesn't happen or do we need to run separate off camera flashes on different channels?
