Aperture Control

Aperture control in photography refers to adjusting the size of the lens opening through which light enters the camera. This opening, called the aperture, can be widened or narrowed to control the amount of light reaching the camera sensor or film. A wider aperture allows more light, useful in low-light conditions and creates a shallow depth of field, blurring the background. A narrower aperture lets in less light, ideal for bright scenes and increasing the depth of field for sharper focus across a wider distance. Aperture settings are typically expressed as f-stops, with smaller numbers indicating a larger opening.
