A striking piece of photography (3)
I believe the answer is:
rap
'a striking' is the definition.
(rap is a kind of striking)
'of photography' is the wordplay.
'of' indicates a hidden word.
'RAP' is hidden within 'photography'.
'piece' is the link.
(Other definitions for rap that I've seen before include "Knock, tap" , "African-American music in which the lyrics are spoken" , "Blame, punishment" , "Knock sharply" , "Knock for par" .)
