Gadget for film or photography that's part of the machine age (6)
I believe the answer is:
camera
But I can't explain it at all! Could you help me understand?
(Other definitions for camera that I've seen before include "Bringing equipment for producing pictures" , "Light-proof box with a lens and film" , "Snapper's kit" , "Nullify" , "Brownie, for example" .)
