"There is an HDR function in mobile photography. What does it do? "

HDR is a high dynamic range, which can combine the best parts of three photos with different exposures into one photo. Using HDR when taking photos, iPhone will automatically store normal exposure photos and HDR photos. If you don't need to keep photos with normal exposure, you need to turn off the "Keep photos with normal exposure" switch in Settings-Photos and Camera.
