Just got a call this evening to do a Halloween themed wedding (like the Nightmare before Christmas) this Friday evening. It will be at 5pm so right at sunset. The back yard is to be decorated like a cemetery and the actual ceremony will be done in the garage that will also be decorated.Need ideas and suggestions on what would be cool ways to use off camera flash to add to the "mood" and get excellent pics. I have 2 canon 580EX's, 2 canon 550EX's, and a canon 420EX.
