Still creator appeared with artist (6)
I believe the answer is:
camera
'still creator' is the definition.
(object which produces photographic stills)
'appeared with artist' is the wordplay.
'appeared' becomes 'came' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'artist' becomes 'ra' (Royal Academician, member of Royal Academy of Arts).
'came'+'ra'='CAMERA'
(Other definitions for camera that I've seen before include "Bringing equipment for producing pictures" , "media producer" , "Brownie possibly" , "Apparatus for taking pictures" , "Photographic instrument" .)
