Truth in documentary making

In my previous post I discussed the idea of creating objective images and dimissed it as impossible. I think all photograhs or films however much they claim to show the truth will always contain bias. However some documentaries are more truthful than others and it is the responsibility of a good documentary maker to try their hardest to be as unbiased as possible. I found this video on youtube. It is a funny video but I think it highlights the immense power a documentary maker has to portray situations as they want, and the responsibility a serious documentary maker has to try an make there films as unbiased as possible.
