Which option describes the focal plane shutter in terms of location?

• A. Global shutter
• B. Leaf shutter
• C. Focal plane shutter
• D. Electronic shutter

Answer: (C)

The main idea here is where the shutter sits relative to the image where the photo is formed. A focal plane shutter is physically placed at the image plane, inside the camera body, right in front of the sensor (or film). It exposes the image by curtains that travel across that plane, so the timing of exposure is controlled at the exact location where the image is captured. This location is what defines a focal plane shutter.

Leaf shutters, by contrast, sit inside the lens itself, not at the image plane, so they aren’t described by location at the image plane. Electronic shutters can expose without a mechanical curtain at the image plane, so the location concept doesn’t apply the same way. Global shutters are about exposing the entire frame at once rather than where the shutter is located.
