Eksponib

Eksponib is a term primarily used in the context of photography and digital imaging. It refers to the amount of light that reaches the sensor or film of a camera. Achieving the correct eksponib is crucial for capturing a well-exposed image, meaning one that is neither too dark (underexposed) nor too bright (overexposed).

Several factors influence eksponib. The aperture of the lens, which controls the size of the opening that lets light in, is a key element. A wider aperture (lower f-number) allows more light, while a narrower aperture (higher f-number) restricts it. The shutter speed, which determines how long the sensor or film is exposed to light, also plays a significant role. A faster shutter speed reduces exposure, while a slower shutter speed increases it. Finally, the ISO sensitivity of the sensor or film dictates how sensitive it is to light. A higher ISO setting makes the sensor more sensitive, requiring less light for proper exposure, but can also introduce digital noise.

Photographers use the interplay of aperture, shutter speed, and ISO, often referred to as the "exposure triangle," to control the overall eksponib and achieve the desired aesthetic. Modern cameras often have automatic exposure modes that calculate these settings, but manual control allows for greater creative freedom.
