Which aspect of photography does the exposure triangle NOT relate to?

The exposure triangle comprises three fundamental elements of photography: aperture, shutter speed, and ISO. These components work together to determine the exposure of an image, affecting how light interacts with the camera sensor.

Aperture controls the size of the lens opening, influencing depth of field and the amount of light that enters the camera. Shutter speed determines how long the camera's shutter remains open, affecting motion blur and the exposure duration. ISO refers to the camera sensor's sensitivity to light; adjusting it can help achieve proper exposure in varying lighting conditions.

Color balance, on the other hand, pertains to the adjustment of colors in a photograph to achieve a natural look or to create a specific mood. It relates more to white balance settings and the color temperature of the light source rather than the core elements of exposure itself. Thus, it does not fall under the purview of the exposure triangle.
