What is a slave group in ref. to 550EX wireless flash? in Canon EOS Mount Posted August 13, 2000 How about setting both 550EX's at the same distance, and using the built-in diffuser of one of them to effectively reduce its output by a stop? This would make the non-diffused flash the main light. <p> SteveB
