any one who has had training will know the group should be built from the centre,Groom to the brides right ,his mother next to him ,her father next to her ,his dad beside his mum,his best man at the end,her mother next to her father her sister beside her ,GP at the front with children evenly spaced and LOOKING at the camera.Anyone coming back with a group like that would be in deep do do,A professional knows that control of the group is almost as important as their talent ,if you cant be in control of whats happening then you shouldn't be in the job
