How can I shoot a distant view with my iphone in order to shoot a clearer distance?

In order to make the images of far and near scenes clear, we often want to enlarge the depth of field, especially landscape photography, which is the most commonly used. \x0d\ In order to obtain greater depth of field, the following points should be noted: \x0d\① Try to shoot with the small and medium aperture of the photographic lens; \x0d\② Try to shoot with the wide-angle end of the zoom lens; \x0d\③ Don't be too close to the main body; \x0d\④ Grasp the correct focusing method, and don't set the focusing distance to infinity in most cases. \x0d\ The greater the depth of field, the smaller the aperture, so the shutter speed will become slower, so pay attention to keep the digital SLR camera stable. \x0d\ When shooting a landscape, if the main scene is less than 20 meters away from the camera lens, it is recommended to focus on it according to the principle of one third. However, if the main scene is more than 20 meters away from the camera lens, it should be focused according to the specific situation: \x0d\① If there is only the main scene in the distance, you only need to focus on the distant scene, and even if you use the large aperture of F2.8, you can get enough depth of field; \x0d\② If there is a main scene in the distance and a main scene in the vicinity, it is suggested to focus on the nearby scene first, and then determine the aperture size according to the distance of the nearby scene. \x0d\ If the focus distance is beyond five meters, you can use F8.0\x0d\ If the focus distance is about two or three meters, you can use Fll or f16; \x0d\ If the focal length is less than two meters, you can use F 16 or F22.
