Getting on with photographer the famous court (3,6)
I believe the answer is:
old bailey
'the famous court' is the definition.
'old bailey' can be an answer for 'court' (Famous English courthouse). I'm not sure about the 'the famous' bit.
'getting on with photographer' is the wordplay.
'getting on' becomes 'old' ('getting on a bit' means 'old').
'with' says to put letters next to each other.
'photographer' becomes 'bailey' (I am not sure about this - if you are sure you should believe this answer much more).
'old'+'bailey'='OLD BAILEY'
Can you help me to learn more?
(Other definitions for old bailey that I've seen before include "Courts" , "suitable for trial in London" , "Central Criminal Court in London" , "London's Central Criminal Court" .)
