Most of my wedding photography and video packages include a free Engagement Photo Session, Engagement Photo Shoot. It's a great way for the bride and groom to get acquainted with the photographer.
It's also great because if you do it early enough you can use the pictures for your invitations. You can also use of the pictures for display at the reception or as favors for your guests.
I usually schedule the Engagement Photo Sessions for a Sunday morning (before the sun and people come out) or late afternoon (after the people leave and the sun goes down.)
You can wear anything you want for the shoot, but I usually suggest a white top and blue jeans for both bride and groom. Clothing should be kept neutral and should match the location. So, for the beach clothing should be white, cream, beige, blue or pastels. Park photo shoots are best in tans, blues and greens. You should also wear colors similar to each other.
The bottom line is to get ready to have lots of fun and take some great pictures.
