Son cuddling daughter appeared before artist: pictures come from this (4,6)

'artist pictures come from this' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'son cuddling daughter appeared' is the wordplay.
'son' becomes 'boy' (synonyms).
'cuddling' means one lot of letters goes inside another (inserted letters are cuddled or held).
'daughter' becomes 'd' (genealogical abbreviation).
'appeared' becomes 'camera' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'boy' going around 'd' is 'body'.
'body'+'camera'='BODY CAMERA'

'before' is the link.

Can you help me to learn more?
