The methodology used is based on the triangulation of three methods that we use in a complementary manner: visual analysis, participant filming and in-depth interviews. The analysis allows us to know the forms of the documentary in our three case studies and in a sample that we have also analyzed to complement the data. The three cases in which we used video as a research tool directly show us creative processes during the production of the documentaries, as well as the link between what is filmed and the significance of the representation.
Thirdly, we conducted in-depth interviews with the directors of the three documentaries. The objective of this last method is to access information directly from the creators, who offer us subjective and direct information about their way of understanding the creative process, the contributions of the technologies according to their professional experience and the relationship created between the representation and the represented.

​

As can be seen in the scheme of Figure 1, by combining these methods we access our object of study from three different perspectives: the final work, the construction of the representation and the author's point of view.
In the method we will include the use of different digital devices to approach our object of study from the three approaches described above, from the analysis of the sample to the treatment of the images obtained during the field study.
