It really depends on number of things. A second photographer is always recommended if you wish to emphasize photo-journalistic photography, or if you have a large number of wedding guests. Two photographers can work together for excellent coverage throughout your day with true photo-journalistic excellence.
For a 200-250 person wedding, we recommend two photographers and one assistant. However, we specialize in shooting weddings that are unique, therefore we customize the photography coverage based on your day and your need.
