长曝光摄影
长曝光摄影，也称为时间曝光或慢速摄影，使用长时间的快门速度来清晰地捕捉场景的静止方面，同时模糊或模糊移动方面。它与传统的摄影实践不同，因为它在很长一段时间内捕获图像，而不是在单个快照中捕获图像。
使用长时间曝光拍摄流动的水（如瀑布或溪流）会在水周围产生雾状效果，使其运动模糊在一起，而其余场景则保持其清晰度。
夜间摄影通常使用长时间曝光来捕捉星迹或其他天体。来自其他来源（如路灯或前大灯）的光线也会在使用长时间曝光拍摄的照片中产生有趣的效果。光绘是另一种技术，它使用长时间曝光和移动光源（例如手电筒或烟花）来创建具有光触的独特“绘画”。
LONG EXPOSURE PHOTOGRAPHY
Long exposure photography, also known as time exposure or slow-shutter photography, uses a long duration of shutter speed to capture stationary aspects of a scene sharply, while blurring or smearing the moving aspects. It differs from conventional photographic practices as it captures an image over an extended period of time, instead of in a single snapshot.
Photographing moving water, such as a waterfall or stream, using long exposure creates a mist-like effect around the water, blurring together its movement while the rest of the scenery retains its sharpness.
Night photography often uses long exposure to capture star trails or other celestial objects. Light from other sources such as street lamps or headlights can also cause interesting effects in a shot that’s being taken using long exposure. Light painting is another technique that uses long exposure and a mobile light source, such as a flashlight or sparkler, to create a unique “painting” with the strokes of light.
