One captures image originated by artist (6)
I believe the answer is:
camera
'one captures image' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'originated by artist' is the wordplay.
'originated' becomes 'came' (coming is a kind of originating).
'by' is a charade indicator (letters next to each other).
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'came'+'ra'='CAMERA'
Can you help me to learn more?
(Other definitions for camera that I've seen before include "shooter" , "Snapper's equipment" , "in judge's private room" , "Common image recording device" , "One never lies" .)
