What is the HDR mode in the camera?

As follows:

Hello, HDR means high dynamic range imaging. My personal understanding is that when dealing with photos with different light and dark, we can make the dark images clear. At present, iphone4s, htc one x and other mobile phones have this function, but mobile phones without this function can also be realized by later software, but the effect is definitely not as good as that of the machine itself.

HDR is not tempted:

What is HDR?

In computer graphics and film technology, high dynamic range imaging (English: high dynamic range)

Imaging (HDRI or HDR for short) is a set of techniques used to achieve a larger exposure dynamic range (that is, a greater difference between light and dark) than ordinary digital imaging techniques. The purpose of high dynamic range imaging is to correctly represent the brightness in the real world from direct sunlight to the darkest shadow.

High dynamic range imaging was originally used only for images generated purely by computers. Later, people developed some methods to generate high dynamic range images from photos with different exposure ranges. With the increasing popularity of digital cameras and the simple use of desktop software, many amateur photographers use high dynamic range imaging to generate photos of high dynamic range scenes, but don't take this as the only purpose. In fact, there are many other applications in the high dynamic range.

When used for display, high dynamic range images are usually tone mapped and used with several other full-screen effects.
