Moment of enlightenment, in camera (8)
I believe the answer is:
exposure
This clue might be a double definition.
'moment' is the first definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'enlightenment in camera' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'of' acts as a link.
Can you help me to learn more?
(Other definitions for exposure that I've seen before include "O pure sex! (anag.)" , "The harmful effects on the body of extreme cold" , "being unmasked" , "Laying open to public view" , "Disclosure - made by a photographer?" .)
