Fieldwork gains those documents, which are necessary to exemplify processes and phenomena under research. Among the multitude of many methods available and used in fieldwork the paper is concentrated on inter-subjective relations and communication between the researcher and the persons supplying information. This relation became in the last decade subject of psychological investigations. The most decisive role is played in this investigation by psychoanalytical views. Ethnopsychological aspects are more and more enlarged and touch the methodology of ethno-psychoanalytical procedures, applied to the fieldwork situation. Furthers aspect are directed to the traditionally used audiovisual multimedia in documentation as it was the case in the last 100 years. In the 70s have been renewed procedures and aspects in inter-personal communication in empirical and experimental projects as applied in the motifs by Sigmund Freud, Bronislaw Malinowski and others, which got a remarkable support in new research. The inner relations in this procedure are exemplified in two schemes: the first shows the infrastructure of relation between the subject of the researchers and the persons he is investigating. The second scheme has to analyze the project of fieldwork, its organization, administration and data retrieval.
