Wedding photographers typically stay for the whole reception, and it is highly recommended to have them present throughout the entire event. By staying until the end, photographers can capture important moments like the first dance, speeches, cake cutting, and other significant events that occur during the reception. This ensures a comprehensive documentation of the day, from the ceremony to the final moments of the celebration. Moreover, staying for the entire reception allows photographers to capture candid moments, genuine emotions, and interactions between guests, contributing to a more complete and memorable collection of wedding photos.
