triangle of exposure

The triangle of exposure refers to the three key elements that influence how a photograph turns out: aperture, shutter speed, and ISO. Aperture controls how much light enters the lens; shutter speed determines how long the camera sensor is exposed to light; and ISO adjusts the sensor’s sensitivity to light. Balancing these three settings is essential for achieving the desired brightness and clarity in an image. Adjusting one element often requires compensating with the others to maintain proper exposure, ensuring the picture looks natural and well-exposed.
