多重曝光(multiple exposure,也叫多次曝光)是一种拍摄技法,这门摄影技术早在胶片时代便已盛行。通过在同一胶片上多次曝光,让几次曝光内容呈现在同一画面。多重曝光的用处很多,比如在一幅照片上分区域拍摄几个不同影像,或让一个被摄物体在画面中出现多次。在传统的胶片单反相机中,多重曝光是一个非常重要的功能,是一种独树一帜的摄影手法。在数码时代,很多相机也设计了多重曝光功能,为大家能轻松拍摄多重曝光作品提供了很好的条件。

By multiple exposures on the same film, several exposures appear on the same screen.

In traditional film SLR cameras, multiple exposure is a very important function, is a unique photography approach. In the digital age, many cameras have also designed multiple exposure functions, which provides a good condition for everyone to easily take multiple exposures.
