I LOVE using natural light when taking photographs. I have worked in a studio with big lights and fancy equipment and there are many benefits to it - the rain won't damper your plans, you can control shadows and create the exact lighting situation you want with some fantastic results, but in my humble opinion nothing beats soft, beautiful natural light, especially when your photographing families.
As a natural light photographer one location opportunity for clients is their own home. Many of my clients request their photographs to be taken in their home because they want personal photographs that capture their family in their own environment, so that in years to come they can look back on them and view them more as 'professional snapshots' of their lives at that time... their child's favorite toy, how their bedrooms were decorated, the tree they used to climb in the garden etc
One major advantage to having a photo-shoot in your home is that children are almost always much happier and calmer being in their own environment, and its possible to really capture their personalities. Here some images from one shoot carried out in the busy home of three gorgeous children two years ago!
