Having a second photographer at a wedding is highly beneficial because it ensures comprehensive coverage of the event from multiple angles, capturing moments that might otherwise be missed. While one photographer focuses on the main events, such as the ceremony and key moments with the couple, the second photographer can capture candid shots of guests, details of the venue, and other behind-the-scenes moments. This dual coverage allows for a richer, more complete story of the wedding day, providing the couple with a diverse collection of memories that highlight both the big and small moments of their special day.
