Aperture Meaning in English
word
Definition
An aperture is an opening or hole, especially one that lets light in. In photography, it refers to the adjustable opening in a camera lens that controls the amount of light reaching the sensor.
Usage & Nuances
Mostly formal and technical, common in photography, optics, and engineering. In photography, "aperture" is often used with 'f-stop' numbers (e.g., 'f/2.8'). Not interchangeable with 'opening' in daily speech. 'Aperture' in general contexts means any hole; in cameras, it's the specific adjustable hole controlling light.
