I require a 4-hour minimum to ensure that I have enough time to comfortably cover all the event details. My arrival time needs to be no later than 1 hour before the start of the ceremony.
It’s usually breaks down to about about 1 hour for ceremony, 1 hour for group photos, and 1 hour for reception and details, with extra hours just spreading it all out or adding to reception coverage. Most clients book 5-8 hours of coverage, so I can get photos from getting ready in the morning, leading up to ceremony, family group, wedding party, bouquet/garter toss, special dances, reception photos, and the grand exit.
I like to be involved in the planning of the schedule to get the most out of the hours you have me for.
