Circular Narrative Description Update

At first the circular narrative idea was some what hard to get my head around, how it was that each set of images had to start and end with the initial photograph. After research into artists who practice in and around the field of circular narrative I have begun to realise what a useful and interesting way of producing work it is. I have also come to realise that it always needs to be under pinned by a conceptual thought/ idea inorder to make it stand out from the many simple story like circular narrative photo-storys. 
Circular narratives have to basically start and end in the same place and have a meaning behind each image which ties the next image into it. Although hard to describe in words, it is seen in many well known films both new and old. It was watching films such as The Shawshank Redemption which helped me to become familiar with the way that the circular narrative works.
