An example of a technique that has been used in the documentaries we have watched is interviews, we have seen this in the documentary “Touching the Void”, throughout the film they cut back to interviews with the people that the film is based on. An interview is when there is an interviewee, a person being asked questions, a interviewer, a person that asks the questions, and a camera man. The interviewer will ask the interviewee questions and then interviewee will answer it. Often the interviewer’s questions will be heard but in “Touching the Void” they aren't giving the affect that the interviewee is just telling the story. They use clips from these interviews throughout the film giving first person reactions too the situations being shown in the reconstruction of their journey.

Another technique that has been used in the documentaries we have seen is undercover filming, we see this in the documentary “Kurt and Courtney”. Under cover filming is when no body in a scene is aware they are being filmed apart from a select number of people who are involved in filming the scene. This happens in “Kurt and Courtney” when Nick Bloomfield gets up on stage at an award ceremony just as Courtney Love has finished her presentation of an award and starts talking about the strange choice of Courtney for presenting the award. We know it is under cover filming by the way the shot is framed and the camera work throughout the scene.

One technical Code is lighting, in all the documentaries we have watched you can see how the film makers have used lighting. In Kurt and Courtney there is largely no extra lighting put into the shots. This is clear through the quality and brightness of some shots. In other parts they make sure that there is sufficient lighting in the shots, for example when they interview the private inspector there is plenty of light that has clearly been added to the scene.
