Hello everyone i've just been introduced to studio lighting and think its a very interesting, jumping straight to the point. is a fill flash better or using a reflector better? and then use the extra speedlight to use as a backgroud to eleminate the shadow? because if i use a speedlight for a fill flash then ill pretty much have to get another one for the backgroud right? Also, those cheap transmiters on Ebay, is it better using those or just using a 580EXii and 2 x 430EX? thank you!
