Opening for a photographer (8)
I believe the answer is:
aperture
'opening' is the definition.
(aperture is a kind of opening)
'a photographer' is the wordplay.
I cannot really see how this works, but
'a' could be 'per' and 'per' is found in the answer.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for aperture that I've seen before include "Opening, gap" , "Eye" , "Opening (on camera, for example)" , "Opening through which light enters a camera" , "Small hole or opening" .)
