I frequent quite a few banquet halls for event photos where the ceilings are at least 40 ft high and the overall space is very large. Note the curtains are not installed most of the time. I do not want to light this as the space is very large. I use a flash bracket and a stofen type modifier. I cannot bounce as the ceilings are in the stratoshere and walls are tinted and far away. So what do I use to get the best shots I can of speakers, wedding guests. dancers etc.
I have looked at Gary Fong Lightsphere which looks compact and pricey and the Rogue Flashbender which sticks up pretty high and . I was at an event last night and used the stofen type directly at the subject and I am not pleased with the effect to say the least. Bounce is very hard at these types of spaces!
