Photograph club athlete (4-6)
I believe the answer is:
shot-putter
'athlete' is the definition.
(shot putter is a kind of athlete)
'photograph club' is the wordplay.
'photograph' becomes 'shot' (shot is a kind of photograph).
'club' becomes 'putter' (a golf club).
'shot'+'putter'='SHOT-PUTTER'
(Other definitions for shot-putter that I've seen before include "sportsperson using strong-arm tactics" , "Athlete throwing heavy ball" , "Athlete hurling heavy metal ball" , "Field athlete" .)
