Lifestyle session vs posed newborn session is a topic of few discussions and blogs. There are different way both might be done and I speak only for myself and the way I do them. I would like first to define what both sessions are.
Easiest way to describe this type of session is to say its documenting real life moments. This session is usually done in your home and forget there is a camera pointed at you. Just go on with what you normally would do. When it comes to newborn lifestyle session it might include, but not limit to: feedings, changing diapers, putting baby to sleep, giving baby a bath, interacting with baby. I would look for best ways to capture those moments without posing you and telling you what to do. End result should be simple, but absolutely priceless memory of having brand new baby in your house. Lifestyle sessions are about natural interactions and usually there is little looking at the camera.
This session is done in the studio. There is a certain flow to it. Parents/siblings images with baby and images of baby alone. I believe in capturing simple natural poses. The main mission of posed newborn session is to create fine art timeless images of you and your new little bundle of joy. There is no need to know how to pose and what to do. I will guide you through session and you will love the way its going to look.
