Prepared to be photographed (5)
I believe the answer is:
posed
'prepared to be photographed' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for posed that I've seen before include "Arranged for pictorial purposes" , "Presented (a question)" , "Struck attitude, perhaps for painter" , "Positioned" , "Faced the camera" .)
