I recently encountered the phrase "Becher typologies". While, I understand the meaning of typology with respect to classification and categorization, Becher typologies do not seem to fit this definition. They appear to involve grids of photos.
What is the meaning of "typology" in photography? Besides Becher typologies, what other photographic typologies are there?
One of the answers at Why are the Becher typologies considered artistically valuable? partially answers this question. This question is not a duplicate of that one because it asks about the "artistic value" of Becher typologies, which is completely subjective. While artistic relevance may be included as part of an answer to my question, I am concerned about the objective definition of typology with respect to photography.
