How to open iphonexs wide angle

Iphone xs opens the camera at a wide angle, which is the default setting of the mobile phone. Just turn on the camera. The iPhone XS is designed with a rear vertical dual camera. Like the previous generation, the iPhone XS still adopts the design of12 megapixel wide angle+12 megapixel telephoto. Among them, the parameters of wide-angle lens aperture and telephoto lens aperture are different. Apple's main camera sensor has been fully upgraded. The unit pixel area of the new wide-angle lens is f1.4 μ m, because the pixel has not changed, it will have a larger sensor, and it may perform better in this case.

Wide-angle lens is a photographic lens with shorter focal length, larger viewing angle, longer focal length and smaller viewing angle than standard lens. Wide-angle lenses are divided into ordinary wide-angle lenses and ultra-wide-angle lenses.

The focal length of a common wide-angle lens is generally 38-24 mm, and the viewing angle is 60-84 degrees. The ultra wide-angle lens has a focal length of 20- 13mm and a viewing angle of 94- 1 18 degrees. Because the wide-angle lens has a short focal length and a large viewing angle, it can shoot a large area of scenery in a short shooting distance. Wide-angle digital camera has short focal length, wide viewing angle and deep scenery, which is suitable for taking photos of large scenes, such as architecture and scenery.

The basic characteristics of a wide-angle lens are its large viewing angle and wide field of vision. The range of scenery observed from a certain viewpoint is much larger than that seen by human eyes at the same viewpoint; The depth of field is long, which can show a fairly clear range; It can emphasize the perspective effect of the picture, be good at exaggerating the foreground and express the sense of distance of the scene, which is conducive to enhancing the appeal of the picture.
