Again photograph changing shore at first over time (7)

'again photograph' is the definition.
('shoot' can be a synonym for 'photograph' so perhaps 'reshoot' is OK for 'again photograph')

'changing shore at first over time' is the wordplay.
I cannot really see how this works, but
an anagram of 'shore' is 'resho' which is within the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is found within the answer.
'time' could be 't' (abbreviation) and 't' is located in the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
