A typology is a set of related photographs of a certain type of object. What exactly this encompasses, however, is a topic of debate. In a typology of chairs, for example, what can and cannot be included? Should they all be of the same material or design? I would say that the exact limits of a typology are impossible to define, but each photograph should bring the same association to the mind of the viewer. Two pictures of chairs painted different colors will make most people have the same thoughts upon seeing them, but a picture of a stool might be entirely different. Also, a typology should include any object that can fall within the set. Blossfeldt’s photos last week seemed meticulously chosen, as if he was looking for a certain aesthetic. With a typology, the artistic element of each picture matters less than the whole, which encompasses everything that falls within a certain range. What exactly the range is, however, can vary between sets.
