I recently was at a Canon Experience weekend, to learn specifically about multi-flash setups. The demonstrator showed how he used three standard camera flash units, controlled by an equal amount of receiver units each. He then had two transmitter units, that the 'students' could try out on a model. Each of the transmitters was able to shoot all flash units.
I dont know any model/serial number/names of the devices that the demonstrator was using, and I am not really interested, other than the general way of how he worked.
I am looking to do a similar multi-flash setup, with the option that there may be two or more photographers working on one model. I looked at the YONGNUO YN560Tx Flash Transmitter with several YN560 flash units.
Question: Can several YN560Tx Flash Transmitters control/trigger the same/selected flash units? Is it possible to handout two or more YN560Tx Flash Transmitters to a group of people to use the same flash units around a model?
