摘要:20世纪最伟大的摄影家安塞尔亚当斯归纳多人的经验而发明的“分区系统”。它是大师留给后人的一份最为珍贵的遗产。自从彩色摄影开始普及后,因彩色胶片及图片制作的技术要求非常严格,所以这些操作一般不是个人可为的。再加上近几十年来的相机产品多附有自动曝光功能,许多摄影爱好者和专业摄影师就不再考虑那么多了,只是将相机设置在自动模式上进行拍摄,。拍摄后的一切工作有都是交给专业图片店去完成,所以分区系统就显得并不是那么重要了。久而久之,许多人把分区系统忘记了,甚至许多从事专业摄影工作的摄影师,也基本不了解什么是分区系统。

   而HDR作为新兴的摄影技术,受到了很多摄影人的喜爱。究其原因,是其强大的画面表现力,能够在一张照片上将丰富的层次表现出来,那么它的原理到底是什么,为什么会有这么好的画面冲击力和表现力?

   分区曝光系统和HDR之间到底有着什么样的关联呢?对我们的实际拍摄又有着什么样的意义呢?
