Is the aperture of the mobile phone as big as possible? How to use the aperture correctly when taking pictures?

When taking photos with a mobile phone, the larger the aperture value, the more prominent the work, the stronger the sense of detail, and the illusory background can highlight the characteristics of the work. However, not all lenses need to use a large aperture, and the aperture should be adjusted appropriately according to the different themes. When taking pictures, we should use the aperture correctly, set the best aperture number of the lens, control the depth of field through the aperture, shoot portraits or still life flowers with a large aperture, and shoot scenes with a small aperture. With the advent of the digital age, many people are becoming more and more accustomed to taking photos with their mobile phones. On the one hand, smart phones are more convenient to carry, on the other hand, they can be quickly shared with friends after taking pictures. Taking photos with a smartphone will also be applied to the aperture. Aperture refers to the lighting device that the lens controls to enter the photosensitive element of the fuselage. Appearance, like a small round hole, the size of this round hole is determined by the aperture and focal length of the lens. Generally speaking, after the light passes through the lens, it refracts to the oxide semiconductor photosensitive element through the aperture, which will enlarge the aperture of the whole lens. In unit time, that is to say, the more light passes through the aperture, the better the shooting effect will be.

The larger the aperture, the higher the lens price. The aperture is directly proportional to the price of the lens. The larger the aperture, the more light enters, and the aperture ultimately determines the quality of the whole photo. In the past, many people were willing to shoot with a digital camera because the aperture of the digital camera can be adjusted, and it can be made larger and smaller freely, and the pictures taken are more clear. Now there are more and more mobile phone manufacturers, especially lens manufacturers. The diameter of the aperture makes the diameter of the aperture bigger and bigger, and the price of the lens is higher. Of course, some zoom lenses with constant aperture have been greatly improved in technology and are more expensive.

If you want to shoot different scenes, the large aperture and the small aperture should be used alternately. When shooting with a mobile phone, if you want to shoot different scenery features, you can use a large aperture and a small aperture alternately. Large aperture is more suitable for shooting portraits or still life flowers. When shooting with a large aperture, the larger the number of apertures and the deeper the depth of field, the more prominent the theme will be. If you simply shoot a flower with a large aperture, the other background will be completely blurred, and the focus will be on that small flower, which is the advantage of a large aperture. This is vividly reflected in portrait shooting. By blurring the background, other sundries around can be erased and only the portrait can be highlighted.

When shooting scenes, it is more suitable for shooting scenes with small apertures. The smaller the aperture, the deeper the depth of field, and the details of each scene can be taken clearly. If matched with a wide-angle lens, you can better shoot large-scale and magnificent scenery. Usually, photographers will use small aperture to shoot light paintings, flowing water, star tracks and other subjects, so as to reduce the aperture as much as possible and reduce the amount of light entering, which can make the scenery more prominent and show details.

The influence of large aperture on mobile phone camera can reach the effect of SLR. Large aperture can bring deep depth of field and blurred background, which can improve the shutter speed when shooting. Usually, when shooting with a mobile phone, the safety shutter should be around 1/30 seconds, so that the shot works have a sense of still life. When shooting night scenes with a mobile phone, keep the lowest shutter speed, and the mobile phone itself will automatically improve the ISO sensitivity. If the aperture is large enough, the picture will not shake after pressing the shutter at the same speed. The works shot with large aperture can achieve the effect of SLR instead.

The aperture of smart phone is as high as F/ 1.7. The bigger the camera aperture of a smartphone with dual-core focusing effect, the better, and the scenery will be more flexible and natural. At present, the aperture of domestic smart phones is at F/2.0, and Oppor 9s does the opposite. Cooperate with Sony to launch a mobile phone with a larger aperture, directly increase the aperture value to F/ 1.7, focus on160,000 pixels, and adopt dual-core focusing technology, which is also the largest aperture that can be achieved in the field of smart phones at present. Such a high aperture value is indeed comparable to the effect of SLR cameras, and it is just around the corner to use smart phones instead of SLR shooting in the future.

In short, the larger the aperture value, the clearer the photo will be, the blurred background and the higher the definition, which can achieve the effect of SLR. However, the size of the aperture should also be selected according to the different subjects. Flowers and portraits can choose a large aperture, while running water and stars can minimize the aperture to highlight the scenery. Judging from the aperture value of domestic smart phones, the aperture number has been raised to F/ 1.7. In the future, surpassing SLR cameras is just around the corner.
