The Exposure Triangle

The Exposure Triangle is a fundamental concept in photography that involves three elements: aperture, shutter speed, and ISO. Aperture controls the amount of light entering the camera and affects depth of field. Shutter speed determines how long the camera's sensor is exposed to light, influencing motion blur. ISO measures the sensor's sensitivity to light; higher values allow for photography in low light but can introduce noise. Balancing these three settings helps achieve the desired exposure, ensuring photos are neither too bright nor too dark, while also affecting the overall quality and artistic feel of the image.
