I just posted this on another forum and would like to try it here,too.
I've been experimenting with all types of devices for use at weddings to diffuse,prevent redeye,get the best(and most efficient) use of on-camera flash with my 580EX.
I've tried the Fong products(LS and Whaletail),the Demb Flipit,ABBC,the 580EX with it's small bounce card,and a couple of brackets.I still am not certain which I will end up using.
I like the quality of light from a bracket(and find the "diffusers" to sometimes be too soft).But the hassle of using the heavy bracket is a consideration.
Why do you "bracket-users" prefer them over the other devices.Also,what is your preferred method of shooting in a large,dark room where bounce surfaces are poor?Thanks for advice!
