Gandhi's Children is probably the most famous film of David MacDougall. The movie takes place in an shelter for homeless children in India and shows the hardships of the lives of children living there and their parents.
From this quote too it is prefectly clear that for MacDougall it is not enough to just go somewhere and film 'objectively' what one sees. An ethnographic film maker should build an intimate,self-reflexive and interpretative relationship with his subject so he can show his audience the reality of the things he had filmed.
This approach is very clear in Gandhi's children. The audience can easily follow the events in the film because of the subtitles, they can get a sense of being there through the intimate cultural knowledge of MacDougall who had selected events and scenes from the kids' lives that are pivotal in understanding the culture in India. Also, the people on the film interact with the camera several times, explaining MacDougal what they are doing and why they are doing it. Surprisingly, this doesn't really bring a level of subjectivity to the film that'd be annoying, rather it brings a different type of objectivity than the one in Forest of Bliss; and in my opinion MacDougall's approach brings India's culture to his audiences a lot closer and in a much more digestable way.
