How does the shutter of a movie camera work?

The shutter of a movie camera is different from the well-known camera curtain shutter and mirror shutter.

The exposure of the film camera is completed by the rotation of the blade.

"180 degree shutter" refers to the clamping angle of the blade opening.

"Speed 50/ 1 sec" means that the blades rotate at a speed of 50 revolutions per second.

When the blade is opened, the film is exposed.

A camera is a very sophisticated instrument.

There is no need to worry that he will be exposed.
