Picture device arrived with artist (6)
I believe the answer is:
camera
'picture device' is the definition.
'camera' can be an answer for 'device' (I have seen 'Photographic device' mean 'camera' so perhaps 'device' could also mean 'camera'). I'm not sure about the 'picture' bit.
'arrived with artist' 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'
Can you help me to learn more?
(Other definitions for camera that I've seen before include "Photograph taker" , "in this, secretly" , "Optical recorder" , "Image recording apparatus" , "Photographic equipment" .)
