Over exposure is a photographic term used when light-sensitive material, such as film or a digital sensor, has received too much light during exposure. This results in an image that is excessively bright, with blown-out highlights and loss of detail in the lightest areas.
Over exposure can occur due to incorrect shutter speed, aperture, or lighting conditions. While it is often undesirable, some photographers use controlled over exposure creatively to achieve high-key effects or a specific artistic look. Understanding over exposure is essential for achieving accurate exposure and preserving image detail in both traditional and digital photography.
