Photograph opportunity (4)
I believe the answer is:
shot
This clue is a double definition.
'photograph' is the first definition.
(shot is a kind of photograph)
'opportunity' is the second definition.
(shot is a kind of opportunity)
(Other definitions for shot that I've seen before include "Crack" , "Zoomed" , "Fired; turn" , "Small drink of liquor" , "pop!" .)
