Which device automatically trips the shutter of the camera at a specified time?

• A. Shutter
• B. Intervalometer
• C. Camera Body
• D. Lens Cone Assembly

Answer: (B)

An intervalometer is the device used to automatically trip the camera shutter at programmed times. It sends a trigger to the shutter according to a set interval or schedule, letting you capture time-lapse sequences or long series of shots without manual pressing. The shutter itself is the mechanical release inside the camera, but it doesn’t schedule when to open; the intervalometer provides that timing. The camera body houses the electronics, but on its own it doesn’t automatically trigger shots unless it has built‑in interval timing. The lens cone assembly is simply part of the lens mount and focusing assembly, not involved in shutter triggering.
