What does the exposure triangle in photography consist of?

The exposure triangle is a fundamental concept in photography that comprises three key elements: aperture, shutter speed, and ISO. Each of these components plays a crucial role in determining the overall exposure of an image, which is the amount of light that reaches the camera's sensor.

Aperture refers to the size of the lens opening, which controls how much light can enter the camera. A wider aperture (represented by a smaller f-number) allows more light in, which is useful in low-light conditions or when a shallow depth of field is desired.

Shutter speed governs the duration for which the camera's sensor is exposed to light. A fast shutter speed can freeze motion, while a slower speed can create motion blur, influencing how movement is captured in an image.

ISO, on the other hand, measures the sensor's sensitivity to light. A higher ISO setting can help in low-light situations, but it may also introduce noise, which can degrade image quality.

Integrating these three elements allows photographers to achieve the desired exposure, creative effects, and maintain image quality under varying lighting conditions. Understanding the interplay between aperture, shutter speed, and ISO is essential for mastering photographic exposure.
