Wild deer getting the old photographic effect (6)
I believe the answer is:
redeye
'photographic effect' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'wild deer getting the old' is the wordplay.
'wild' indicates anagramming the letters.
'getting' is a charade indicator (letters next to each other).
'the old' becomes 'ye' (resembles a historical spelling of 'the').
'deer' with letters rearranged gives 'rede'.
'rede'+'ye'='REDEYE'
Can you help me to learn more?
(Other definitions for redeye that I've seen before include "Fish; cheap whisky" , "Describes the first flight in the morning" , "Flash-induced effect on photo" , "Effect of flash seen in portrait photos" , "Photographic problem" .)
