高动态范围成像英语:High Dynamic Range Imaging,简称HDRIHDR),在计算机图形学与电影摄影术中,是用来实现比普通数位图像技术更大曝光动态范围(即更大的明暗差别)的一组技术。高动态范围成像的目的就是要正确地表示真实世界中从太阳光直射到最暗的阴影这样大的范围亮度。

高动态范围成像最初只用于纯粹由计算机生成的图像。后来,人们开发出了一些从不同曝光范围照片中生成高动态范围图像的方法。随着数码相机的日渐流行以及桌面软件变得易于使用,许多业余摄影师使用高动态范围成像的方法生成高动态范围场景的照片,但是,不要将这作为它唯一的用途,实际上高动态范围还有许多其它的应用。

Example of HDR time-lapse video

High-dynamic-range imaging (HDRI or HDR) is a technique used in imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard digital imaging or photographic techniques. The aim is to present the human eye with a similar range of luminance as that which, through the visual system, is familiar in everyday life. The human eye, through adaptation of the iris and other methods, adjusts constantly to the broad dynamic changes ubiquitous in our environment. The brain continuously interprets this information so that a viewer can see in a wide range of light conditions.
