Dire photos misrepresented ministers collectively (10)
I believe the answer is:
priesthood
'ministers collectively' is the definition.
(priests are church ministers)
'dire photos misrepresented' is the wordplay.
'misrepresented' indicates anagramming the letters.
'dire'+'photos'='direphotos'
'direphotos' with letters rearranged gives 'PRIESTHOOD'.
(Other definitions for priesthood that I've seen before include "cleric's office" , "future for seminarian" , "Minister's office" , "Ordained order" , "office in church" .)
