I'm seeing alot of photographers that seem to have a romantic portrait session of the bride and groom on their big day at sunset/in a field, etc. Are those shot on the actual day of the wedding? Do some photographers photograph those shots the day before?
I'm wondering what the role of the bride/groom will be (host/hostess?) and if it's polite to run off to a totally different location for photos, leaving the guests at the ceremony/reception hall (mine will be at the same venue).
