What does the icon on the camera of Apple 7 mean?

There are five icons on the Apple camera, namely: flash, HDR (high dynamic range image) and Live? Photos, timed shots, filters.

1, HDR (high dynamic range image), simply put, is to make the picture better reflect the visual effect in the real environment through the method of multi-Zhang Hecheng. Compared with ordinary images, HDR can provide more dynamic range and image details. Many people actually don't know what HDR is and have never used it. HDR means to make your photos clear in highlights and shadows. Bian Xiao didn't say too many details. By comparing the pictures below, you may see the benefits of HDR. Can make the details of the dark part of the photo clearer. However, you don't have to use HDR if the light is good.

However, when we turn on HDR, the phone saves two photos by default, one is a normal photo and the other is a photo after turning on HDR. If you don't want to keep normal photos, you can go to Settings-Photos and Cameras-Keep normal exposure photos. Turn off this option!

2, live photo, that is, the photo you took, has a 3s dynamic record before and after. On the photo, press it slightly hard to trigger 3d touch, which makes the photo move, similar to the moving picture effect.

3, timed shooting, generally used for self-portraits or group photos, if it is a group photo, put the phone in front of the crowd, and then set the shooting time.

There are 3 seconds and 10 seconds to choose from. After choosing, press the shutter and you will join the crowd quickly. In a few seconds, the shooting will be completed automatically!
