The Art & Architecture Thesaurus
The Art & Architecture Thesaurus maintained by the J. Paul Getty Trust and is useful in standardizing vocabulary to ensure uniformity of term use and that the relationships between terms are recorded. This website only deals with photography which is a small part of the complete thesaurus however where possible I use standardized vocabulary to ensure compatibility.
