Photograph a kind of dragon (4)
I believe the answer is:
snap
I believe this is a double definition.
'photograph' is the first definition.
(synonyms)
'a kind of dragon' is the second definition.
(I've seen this in another clue)
(Other definitions for snap that I've seen before include "Break - children's card game" , "Cut" , "game of cards" , "Unpremeditated - bite" , "Quick photograph - impression" .)
