Over the years we all observe patterns in our daily lives. A good portion of the time, people make decisions are based on their experience and best judgement and everything works out great. There are a few times where, as a friend, I have pressed a little harder than I would otherwise because my experience taught me that there are some things we don't know we don't know...until we go through the process ourselves. Our nanny, from years ago had a baby. And didn't want the birth to be filmed. I told her "I got it, but you MAY feel differently after your little angel is in your arms." Then, you MAY wish you could watch the delivery over and over, for the rest of her life. "And if you still don't want the video, after Lily is born, then you can toss it." She agreed. And has thanked me countless times over the years since.
So, back up to your wedding. And Cinematography. It may be an item you don't "need." Agreed. But I want to put my two cents in this bucket. You plan and plan. You research and craft. You ask around, you google, you pin. And you spend your budget carefully and with intention. But on your wedding day, YOU never get to watch the bride walk down the aisle. YOU never get to see the ice blocks covered in sushi and sashimi (my wedding) at cocktail hour. YOU never get to see everything the way your guests will see it. So, my friends, maybe cinematography is the gift you give YOURSELF after all your hard work. And one you can enjoy over and over again with your family, your children and grandchildren in the years to come.
