You should provide an in-text reference for any photograph that you reproduce in your work – and when you refer to a piece you have seen in its original format but not reproduced in your work.
If you have reproduced the photograph, the citation would normally be given after the caption/title of the piece. Include the page number(s) if coming from a printed source.
If you have not reproduced the photograph, follow the usual reference format for the source. You may do this if you have seen the original artwork such as a painting, photo, sculpture, building, dress, design, installation etc., at an exhibition, in a gallery, fashion show, museum, personal collection etc., and would like to reference it.
