So I had a thought the other day while using my cheapo cowboy studio radio trigger. I only have one transmitter and one receiver. For the longest time I figured I could only have one off camera flash (that’s not an optical slave). I have a 430EX II and a 580EX II. I can trigger the 430 with my 580 because the 580 acts as the master and it is all still lovely ETTL.
Well I thought to myself, if I can use the test light on the 580 and it triggers the 430, then why can’t I set the 580 on master and the 430 on slave and use the cowboy studio to trigger the 580 which in turn will trigger the 430.
Well whaddya know, it worked! Granted all of the flashes have to be manually configured unless I do ratio on the 580, I am pretty satisfied at now being able to have 2 off camera flashes without the use of more equipment.
