How is a documentary realized? Does some formula or method exist to take to end a filming of this type? How do suitable prominent figures reveal themselves? Is it necessary to register material how much? How does creative process itself develop? More of at some time, we have listened to these and many other interrogations on the documentary process and the multiple stages that compose its temporary space structure. Nevertheless, in many occasions, I have seen and hear like some colleagues ignore and unknow basic cinematographic principles, demonstrating their arrogance and lack of respect towards the properly such documentary genre. In virtue of that, has seemed to me to be pertinent to write around the above mentioned subject matters across the experience itself. It is what I do.
