Arrived with artist's photographic device (6)
I believe the answer is:
camera
'photographic device' is the definition.
(I've seen this before)
'arrived with artist's' is the wordplay.
'arrived' becomes 'came' (come can mean to appear or arrive).
'with' means one lot of letters go next to another.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'came'+'ra'='CAMERA'
(Other definitions for camera that I've seen before include "One never lies" , "One creating image" , "Brownie possibly" , "optical device" , "brownie perhaps" .)
