What does HDR mean when I take pictures with my mobile phone?

The abbreviation of Range means "high dynamic range". Expose different pictures with multiple pictures, and then superimpose them into one picture with software. The advantage of HDR photos is that you can get a photo with details of shadows and highlights, while in normal photography, you may only choose one of them. When shooting in a large light ratio environment, ordinary cameras cannot record extremely bright or dark details due to the limitation of dynamic range. Even in the case of high aspect ratio, the photos processed by HDR program can get better levels than ordinary photos, no matter the highlights or dark parts.

Simply put, HDR photos are:

1, the bright place can be very bright.

2. Dark places will be very dark.

3. The details of the light and dark parts are obvious.
