Create a Documentary Notebook to write down all of your ideas and keep your research organized. Watch historical documentaries and write a list of what you think makes a great historical documentary
Make sure you have access to -a computer -a video camera -editing software -supplies: batteries, blank DVDs or videotapes, paper, pens, props
Research the topic first. One way to choose your topic is to select a commonly known story and then find a different angle that brings something new to it. Remember that there are many unknown stories that also should be told. Regardless of the topic you select, choose one that truly interests you, and remember to put it into historical context.
Keep a database. It is important that you have a database where you keep track of all of the information you are gathering. A database is simply any place where you can collect and easily access your sources and production materials.
Create a Timeline. Before you jump into your project, it is a good idea to create a preliminary timeline of when you want to finish important steps along the way, especially the start and end dates of pre-production, research, production, and post-production.
Create a budget. On the practical side, you need to have a sense of the costs of doing this project. Remember you don't have to break the bank to make a film. Spending more money does not make a film better in quality.
