let'em duel it out.
I say we just let them duel it out. 10 paces turn and fire.
On camera left 1 Canon 580 EX II (master), mounted and fired into white shoot through umbrella at 1:2 power. On the floor below me, a bare Canon 430 EX (slave) at 1:2 power pointed right on the back of the chair. On camera settings was 1/200 sec, F8, ISO 100. Fired using a Canon off-shoe cord and optical RF to fire the slave.
