Moment of enlightenment, in camera (8)
I believe the answer is:
exposure
This clue could be a double definition.
'moment' is the first definition.
The answer and definition can be both human attributes as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'enlightenment in camera' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'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?" .)
