Expert's popular photograph (7)

Ross

I believe the answer is:

hotshot

'expert's' is the definition.
(hotshot is a kind of expert)

'popular photograph' is the wordplay.
'popular' becomes 'hot' ('hot' can be similar in meaning to 'popular').
'photograph' becomes 'shot' (shot is a kind of photograph).
'hot'+'shot'='HOTSHOT'

(Other definitions for hotshot that I've seen before include "Showily successful person" , "ace" , "Important person" , "Top player" , "Expert" .)

I've seen this clue in The Telegraph.
