Having an engagement photo session is very common for a wedding couple of have. In addition to having a nice set of photos for the future, it would also be nice to have a photograph that you can use for the wedding invitation. Another reason maybe to have an engagement portrait to be displayed during the wedding, as well as using the photos from the session for a video presentation.
There is another reason that I think, as a wedding photographer, that an engagement photo session is really important. This is the time when the wedding couple can get acquainted with their photographer from the important perspective of how he takes photos. In the one hour or so during the session, the you will be able to see how sets up poses for example. You will also get a sense of timing. And the nice thing, this all happens in an environment that will be more casual and relaxing.
For me, as the photographer, this is a really great time for me to be able to “teach” you on how to pose. I will take this opportunity to consider the various angles. The numerous photos I will take will give me a chance to learn about you as a couple, which I will use during the wedding. The nice thing is that during that wedding day, we will already know each other.
