Recommended citation for own photograph

In my thesis I have several photographs, which have captions in the form of

Photograph of building X, taken on date by the author of this thesis

Citations to referenced papers follow the [1] (BibTeX plain) format. My supervisor suggested to reference my own photos by using the following format:

Building X (my name, year)

This however follows a different reference style (APA style) and may be confused with a reference to a paper. What are the recommended styles to follow for own made photographs while making sure that I am the actual producer of the photos (as I've seen theses that commonly take photographs from other sources without actually referencing the source)?
