First of all, shaking hands is definitely the most influential factor in image quality. Even in normal non-night mode, the night mode is more serious, and the shutter will automatically lower! You can use a tripod or shoot regularly, or control the headphone cable. Don't magnify the anti-shake action during practice.

IPhone 1 1 has no optical zoom. If you enlarge it several times, you just cut the photo and enlarge it, which will dilute the picture quality. Get close to the subject and improve the imaging resolution!

Avoid the situation that the background is too violent when shooting in backlight, which leads to the unclear fog surface of the subject. You can turn on Smart HDR in settings, which is usually turned on by default.

Then you can slightly lower or raise the exposure in the shooting interface to adjust the sharpness of the subject!

When shooting a specific in-focus object, it is necessary to make clear the object to be shot, and then shoot after focusing, otherwise the autofocus of the camera may not be on the desired object.
