Doc mini task

A documentary is a factual program to inform people about things that are happening around or they could me more specific personal subjects.

An expository documentary talk directly to the viewer, they are rhetorical, trying to persuade the audience a certain way.They will usually have a voice over, usually a powerful authoritative voice so the audience are more inclined to pay attention.The way an expository documentary is edited is very smooth, it's used in a way to back up every thing the voice over is saying.  An example of an expository documentary is Wild China a nature documentary about China. It is an example of an expository documentary because its very one sided, trying to make it's viewers think a certain way.

Observational documentaries are documentaries where film makers go somewhere and just film things without interacting with anything. There are never any interviews because the camera crew have to act like they're not there. In there purest form they wouldn't be any voice overs but in a lot of cases there are voice overs to explain whats happening. these are very typically nature documentaries such as the BBC's planet earth series. This is an example of an observational documentary because none of the camera crew interfere with anything they're filming, they just let it all happen. Although there is a voice over throughout the whole thing so it's not an observational documentary in it's truest form.

In an interactive documentary the film maker is present, they are presenting the documentary, the personality of it. There tend to be a lot of interviews in this style of documentary, but usually informal interviews. They are usually filmed with minimalistic camera crews, this is because they usually follow people so it'd be hard to carry around massive cameras and equipment.   This form of documentaries are criticised for a very heavy use of editing sometimes  causes misinterpretation for the viewers. Sometimes they have to edit so heavily to protect peoples identities. An example of an interactive documentary is any Louie Theroux, documentary, he is always the personality for his documentaries always in front of the camera interviewing. Most of the interviews he does are also informal, almost just like he's having a chat with them. They're also filmed in a very minimalistic way, witch a small camera crew.

Reflexive documentaries are much more experimental than the other types of documentaries. they will often not comply to documentary conventions.Sometimes it's difficult to fully follow a reflexive documentary because they can go so far away from the conventions of typical film making it's difficult to make sense of some things.It's very much in the editing how they usually become a lot more experimental. An example of an Reflexive documentary is "A man with a camera", this documentary is about how a film is usually filmed and produced etc. This film was very experimental and didn't follow typical documentary conventions.

Performance documentaries are documentaries that use a lot of reenactments of real life events, these re enactments are usually dramatised to make it more exciting to watch, this could have a negative impact as it could misconstrued what the documentary is about and what actually happened in the events they're recreating. A good example of performance documentaries is tongues untied, which is about giving gay black men a voice. senses in this documentary were re enacted.

I think documentaries should be edited to make a sense of the story and to make it more entertaining for the viewer, although they shouldn't be edited to the point that the message of the documentary is missed. It shouldn't miss represent what it's about. But the main purpose of a documentary is to entertain so it should be edit to an extent.
