Which is the correct term for the opening size in the camera lens?

Explanation:
Aperture. It’s the adjustable opening inside the lens that controls how much light reaches the sensor. A larger opening (lower f-number, like f/2.8) lets in more light and creates a shallower depth of field, making backgrounds blurrier. A smaller opening (higher f-number, like f/11) lets in less light and increases depth of field, keeping more of the scene in focus. This opening works with shutter speed (how long the sensor is exposed) and ISO (sensor sensitivity) to determine overall exposure. Shutter speed, ISO, and sensor size each influence exposure or image characteristics in different ways, but the opening size of the lens is specifically aperture.
