1. Making sure that you are ready on time will give the photographer enough time to get the best possible shots prior to the wedding ceremony. The more time you give your photographer, the higher quality memorable photos you will have.
2. Practicing posing for your wedding photos is very helpful for the photographer and your own comfort. If you are uneasy about how you think you may look when you are posing your facial expression will show it. It helps to practice in a mirror or have a friend take a fun photoshoot of you.

3. Designating a person to help coordinate group photos is very helpful. The photographer is responsible for taking a number of formal pictures and having someone such as the wedding planner help gather the family helps make everything very efficient.
