I shoot Lifestyle Portraits. When I first started this was a relatively new niche for mainstream portrait photographers. Its intention is to describe a non-traditional portrait of people in the moment and without poses. When photographers started latching on to the idea it was often because not posing people sounded easy. People are not posing all day!
But I've seen a lot of photographers produce mediocre prints claiming to be "lifestyle" and looking a lot more like Uncle Bob's snap shots at the park. Just because a kid isn't looking at the camera, doesn't make it a lifestyle portrait. If you are going to commission a portrait it should be something that you cannot achieve on your own with your Nikon Coolpix. It should evoke a feeling.
Lifestyle portrait sessions involve a variety of photos to tell a story. They require a meaningful location and are easier with a comfortable subject. I prefer natural lighting for a truly natural portrait and it helps me focus on people and not cords. And they involve direction.
Just because I know what a good portrait is, doesn't mean I can always achieve greatness. Sometimes it works better than others. This session was one of those times. I could have hung around and played with these girls all day.
