Ethnology and cultural anthropology are characterized by the field research and ethnographic collection of material. Recording and transcription seem to be issues of ethnoscience that have already been resolved many years ago. The relevance of their use in science, e.g. by intercultural comparison,was getting lost with the use of more illustrative and available photo and film recording. Later on, the complicated schemes of interpretation of the empirical knowledge were a burden for the disciplines themselves; they were literally overloaded by sign systems. The issues have been methodologically addressed by resignation to the descriptive documentation. This paper is pointed at the methodological discourse of the visual documentation, visual data analysis and interpretation in research of the cultural heritage.
