So a friend of mine has a T3i and a 580 ex and she is trying to do OFC. She's trying to figure out how to trigger it to fire. I looked in the manual and apparently you have to have the 580ex operate as a "transmitter" to another flash, so that the second flash fires. Is this true? Other than the ST-E3-RT, is there another way? I'm assuming that there has to be a transmitter in the hot shoe, and that the T3i doesn't have a built-in transmitter. Thanks
