Another option is to think about saying NO. Weddings and photography are a sneaky plan of the devil to fracture families and it works. Sickness is a valid out. Use it!!!! Find some way out. I'd rather have teethe pulled by terrified amatuers (stolen fromW.S.Gilbert, I confess) than do another wedding. Save yourself first, then the women and children.
Scratch what I said above; this guy has the right idea.
