I know you trust and love your family, but trust only goes so far in saving the memories from your wedding. Recently I performed a wedding ceremony at a prestigious hotel and the couple asked a favorite uncle to videotape the ceremony. Apart from the fact that the gentleman had no idea where to stand (and not stand,) he was not dressed to blend in and not draw attention to himself. He rotated around the bride and groom throughout the ceremony. Not to mention, he almost burned up the ceremony site by knocking over more than a dozen lit candles. The choice to use a friend or family member resulted in and often does result in lots of cut off head shots, foot shots, jerky video footage, poor transitions, and bad lighting.
Heed my advice, seek out a professional. View examples of the videographer’s recent work. Ask your coordinator or officiant to recommend someone to you. Remember, this is the video you will one day show your children and grandchildren.
