[sorry for the delay - my family is in town and that always makes me a tad more busier]
to ensure you capture every moment of the day [especially moments that you can't be a part of but have planned for], you may want to give your photographer a list of pictures to take!
sometimes it's the details that you've worked hard on: menus, programs, place cards, table runners, party favors, water bottles, fans, parasols, the bottoms of your shoes, etc.
sometimes, it's just moments: when the flower girl gets her hair done, the groom and his best man showing off their socks, or the bridesmaids singing a special song for the bride!
Remember, it's your day and the photos are the only lasting impression...
