Long exposure is a photography technique that involves using a slow shutter speed to capture images over an extended period. This allows for the accumulation of light, resulting in unique effects such as smooth water surfaces, light trails from moving vehicles, and the blurring of clouds. It is commonly used in landscape and night photography to create a sense of motion and time. To achieve long exposure, photographers often use a tripod to keep the camera steady and may employ filters to reduce light entering the lens. This technique can transform ordinary scenes into captivating images, highlighting the beauty of movement and light in a single frame.
