Swings camera back to take photo (4)
I believe the answer is:
snap
'photo' is the definition.
(I know that snap is a type of photo)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for snap that I've seen before include "Sudden break" , "A walk in the park < to shoot" , "piece of cake" , "Cut" , "Break - children's card game" .)
