In this wedding the minister asked me to be in the back, during the vows. The problem was the lights were very dim. so I set two light stand, with Canon 430 EZ flashes, just out of sight bounced from the ceiling and with Sto-fen omni bounces it provided enough light for a decent exposure. Along with another flah on a camera bracket and a Canon off shoe cord.

They were triggered with the Chinese radio triggers off of Ebay
