Preparation-Research into documentaries

Because I was working by myself i sat down and discussed which genre would be the most easiest and effective to film with my Media Studies teachers. We ultimately came to the decision of the documentary genre and started looking at trailers and film makers on YouTube. As I already knew about Sir David Attenborough i also wanted one more person to research and my teacher suggested to me a man called Nick broomfield and from there I began to piece different areas of film- making/documentaries.
