Cite Them Right Harvard referencing style:
Look under the tab "Media and Art" and find "Photographic Prints or Slides" suggested elements for a reference are:
Artist/Photographer's name (if known), Year of production. Title of image. [type of medium] and Place of Publication
For Example:
Beaton,C. (1956) Marilyn Monroe [Photograph]. (Marilyn Monroe's own private collection).
Referencing your own photographs, it should be as above with your name and year taken. Give it a title and reference it as a photograph from your own private collection.
