Camera Shutters and how they work
There are 3 types of camera shutters being used these days. The first is the manual shutter which consists of 2 curtains, front (or first) and back. The manual shutter is used in most Dslr and mirrorless cameras. The way the manual shutter operates in both types of cameras is similar with one big exception.
Since Dslr cameras use a mirror to reflect the light from a scene to the view finder or LCD screen, it must flip up so that the light is exposed to the shutter curtains. Then the front shutter slides down exposing light to the sensor behind it. The rear curtain slides down to stop the the exposure at the shutter speed chosen.
