His camera captured trick (4)
I believe the answer is:
scam
'trick' is the definition.
(I've seen this in other clues)
'his camera captured' is the wordplay.
'captured' indicates the answer is hidden within the clue.
'SCAM' is hidden within 'his camera'.
(Other definitions for scam that I've seen before include "Dubious operation" , "Con trick" , "Fraudulent scheme, swindle" , "Screw" , "Fraudulent business scheme" .)
