There are tons of reasons why you should have an engagement session before you big day.
You can never have enough images of the two of you! An engagement session is the best practise for the portraits on your wedding day. You get to know me, your wedding photographer, you will get more comfortable in front of the camera, I get to know you, learn what makes you giggle, or if you are a more reserved couple... You learn how to pose in an unposed way ;)
And in the end you will have beautiful photos :)
