If you don't care about finding theaters to screen your film, then it is a simple matter to make a documentary. But while most ordinary persons can, at best, make a recording of some basic material, there is a lot more that is needed to make a good film, such as editing, originality, creativity, aesthetic input, sincerity, and permeation into real life.
如果不在乎放映管道，拍紀錄片非常簡單，一般人最能做到的就是把素材紀錄下來。但能不能成就好作品，牽涉其他面向，如剪接組合、原創力、藝術觀照點、態度的誠懇、生活的沈澱等等。
