Camera part thrust haphazardly, but with energy (7)
I believe the answer is:
shutter
'camera part' is the definition.
(I know that shutter is part of camera)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for shutter that I've seen before include "camera component" , "Device on a camera, it opens and closes" , "Hinged window blind" , "Moveable window screen" , "Hinged window cover" .)
