Hello all. I am shooting a 50th wedding aniversary party this Saturday night. We are shooting at a beautiful Mission with evening light. However, my client just informed me that they want a group photo with 68 adults and seven children. WIDE...I know. Any recommendations for me on how to light this for fill? I have Novatron's with 36" boxes and multiple speedlites. Also recommendations on Aperture settings...F11? smaller? I have Canon 30D.. 17-40L, 50 1.4, 24-105L at my disposal. Appreciate your thoughts.
