His camera captured swindle (4)
I believe the answer is:
scam
'swindle' is the definition.
(I know that scam is a type of swindle)
'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 "Con trick" , "Hoax" , "Dubious operation" , "Fraud, trick (slang)" , "fiddle" .)
