Delete some camera settings (5)
I believe the answer is:
erase
'delete' is the definition.
(erasing is a kind of deleting)
'some camera settings' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ERASE' is hidden within 'camera settings'.
(Other definitions for erase that I've seen before include "Put out of mind" , "Remove from memory" , "Rub out, expunge" , "score" , "Take out" .)
