This is an important day, so the photographer should be working for you and therefore it is the photographer's responsibility to cover the event as you wish. So don't get compromised into making a choice between one fixed package or another. Always remember, this is your wedding day not the photographers and therefore you are entitled to call the shots.
Of course, with over 25 years' experience I'm happy to help you plan your wedding and advise couples on what can be done on the wedding day.
