Camera settings refer to the various adjustments you can make on a camera to control how a photo is captured. Key settings include aperture, which affects the amount of light entering the lens and the depth of field; shutter speed, which determines how long the camera's sensor is exposed to light; and ISO, which controls the camera's sensitivity to light. These settings work together to influence the overall exposure and quality of an image. Understanding how to balance these elements allows photographers to achieve their desired effects, whether capturing a bright landscape or a low-light scene.
