Explain long-exposure technique as you would to a capable student, in 3-4 sentences.

# Long-Exposure Photography Long-exposure photography uses a slow shutter speed—typically several seconds or longer—to capture the movement of light and objects over time. While stationary elements remain sharp, moving subjects like water, clouds, or car headlights create beautiful motion blur or light trails. To prevent overexposure from all that incoming light, you'll need to use a narrow aperture (high f-number), low ISO, and often a neutral density (ND) filter to darken the scene. A tripod is essential since any camera movement during those long seconds will ruin the shot's sharpness.
