The big moment!
In a traditional ceremony, the photographer would normally be poised and ready to capture the bride’s big arrival, along with the groom’s first reaction.
Then the photographer would normally keep out of the way for the rest of the ceremony. This can often mean retreating to somewhere near the back of the ceremony, and using a longer lens to unobtrusively capture the events without distracting from the ceremony itself.
Some venues have some restrictions on where the photographer can be positioned, whereas some will only allow the photographer to pick one location and then to stay still. This is something that your photographer can discuss with the venue when you book them.
During the ceremony itself your photographer will aim to capture all the big moments: readings, performances, the rings, the first kiss and the big exit as a newly married couple!
