How to use Apple's dual cameras?

Question 1: How to use the Apple 7plus dual camera Hello, the Apple 7plus dual camera is very powerful.

On the back of 1 and iPhone 7 Plus, there are two cameras with120,000 pixels, namely a wide-angle lens and a telephoto lens. The former uses F/ 1.8 aperture, and the latter uses F/2.8 aperture.

2, telephoto lens: this 56 mm lens can help you avoid the common photo distortion problems when taking photos such as portraits.

Wide-angle lens: Wide-angle lens has a wide angle of view, which can take all the scenery into the picture; You can separate the close shot from the long shot and emphasize the sense of distance; The scene is deep, which can make both the close shot and the long shot in focus, and the effect of shooting people is great.

I hope it helps you.

Question 2: How to use the dual camera on Apple 7plus? If you have an iphone7plus, you can realize your SLR camera dream. Iphone7plus dual camera has the effect of SLR camera, which meets the needs of photographers who want to use SLR camera. In many cases, it even exceeds high-end SLR cameras.

Iphone7plus removes the original antenna line, making the fuselage more concise and refreshing. The dual camera also solves the problem that the camera bulges due to the thinning of the mobile phone.

Iphone7plus uses dual cameras, one is a wide-angle lens (F 1.8)+ a telephoto lens (F2.8), and both lenses are120,000 pixels, and the focal length can be adjusted by 10 times. If it is more than 2 times, it becomes digital zoom. Photographers only need to compose pictures without focusing, which is more conducive to capturing pictures. Will make the portrait stand out. When zooming to twice the focal length, iphone7plus will enable 56mm lens for optical zoom, while iphone6plus can only rely on digital zoom.

Dual cameras can also cooperate with shooting. Theoretically, it is12 million pixels+12 million pixels = 24 million pixels. Thereby increasing the light input of the camera, enhancing the sensitivity and brightness of photos, improving the image quality and effectively reducing dry spots.

The Iphone7 plus has been equipped with four flash lamps instead of two. It will be adjusted according to the ambient color temperature, and the dual camera of iphone7 plus also has anti-shake function. When we use Apple's dual cameras in dark light, Apple will stop using the telephoto lens, and there is no optical zoom function, only the digital zoom that can be extended to 10X. The image of iphone7plus at twice the focal length is a clear image that we have never seen on a smartphone before. All kinds of details can be photographed. For those who like to take pictures, choosing iphone7plus is nothing more than a good choice.

Question 3: How to use the dual camera of iphone7 Compared with the iPhone6s series, the biggest change of iPhone7 and iPhone7 Plus is probably on the back of the fuselage. In addition to the most obvious "crown antenna", the camera of iPhone7/7 Plus has also changed significantly: the camera of iPhone7 is more prominent, while the camera of iPhone7 Plus simply adopts dual cameras. The convex camera will undoubtedly destroy the beauty of the fuselage. Why does iPhone7/7 Plus adopt such a design? Mainly because of the rapid development of Samsung S6/S7 series in the field of photography in the past two years, iPhone is no longer the benchmark in the field of photography. The application of large aperture, large sensor and optical image stabilization makes Samsung S7 the best mobile phone for taking photos at present. The biggest feature of this phone and the subsequent S7 Edge and Note7 is that there is a huge camera behind it.

Although the performance of smart phones is constantly improving, the volume of electronic components such as CPU and memory is constantly shrinking. But only one component has become bigger, and that is the camera of the mobile phone. Because no matter how mobile phone photography technology develops, it must follow the most basic optical principle, that is, the larger the lens volume, the more light it enters, and the better the imaging effect. If you want to take clearer photos, it is inevitable to make the camera bigger.

A larger camera can use a larger aperture and have a larger CMOS sensor area, which are the two most important parameters to determine the photo effect. On professional SLR cameras, we can make the lens very big and long, but not on smart phones. Apple's iPhone has always taken a thin and light route, and each generation of iPhone will strive to be lighter and thinner, and it is impossible to put down a larger camera component. Although Apple has a camera technical team of 800 people and a nearly perfect camera software algorithm. However, the field of photography is "crushing the bottom people". No matter how the camera of Apple iPhone is optimized in software, the innate gap in hardware can't be made up.

Through the photos of the real machine that have been exposed, we can see that the upcoming iPhone 7 has abandoned the 3.5mm audio interface for thinness, but the lens has become more prominent, because it is impossible for Apple to continue to reduce the thickness of the camera in order to ensure the photo effect of the iPhone 7. Otherwise, what do we compare with Samsung? In addition, it is said that the iPhone 7 has also added OIS optical image stabilization, which is one of the reasons why the iPhone 7 camera is more convex. The reason why iPhone 7 Plus uses two cameras is to increase the area of CMOS sensor in disguise, which is the same as Samsung Note 7 using a single larger camera.

To sum up, smart phones must make a fuss about the camera size if they want to improve their camera level. A big camera may not take a good picture, but a good mobile phone camera will definitely not be small. Therefore, the more convex camera of iPhone7 and the dual camera of iPhone7 Plus are necessary.

Question: How to use the dual camera behind the iphone7plus? If you have an iphone7plus, you can realize your dream of a SLR camera. Iphone7plus dual camera has the effect of SLR camera, which meets the needs of photographers who want to use SLR camera. In many cases, it even exceeds high-end SLR cameras.

Question 5: How to switch the dual cameras on Apple 7plus? You can't switch cameras manually, that is, you can't use whichever you want.

In portrait mode (because IOS 10 adds depth of field mode), the auxiliary camera in the middle will be turned on. Other modes still use the main camera outside.

Question: What's the use of dual cameras on iPhone 7 Plus? The configuration of dual cameras is an assumed photography mode. Computational photography uses the built-in algorithm to analyze the information collected by two cameras to make up for the deficiency of a single camera. The existing automatic panoramic mosaic technology adopts the idea similar to computational photography, and the HDR high dynamic range photography technology that takes multiple photos and then merges them into one photo is also similar. People's way to improve the defect of single camera is simple and rude: just add more cameras. So in essence, dual cameras are just the first step in this rude solution.

Apple's dual camera configuration is not an eye-catching innovation, but they did a good job. The whole dual-camera system doesn't have too many calculation parts, only the background blur operation should be handed over to the software. At present, there is no corresponding software for the iOS system, but Apple will soon launch a corresponding system upgrade. IPhone 7 Plus is equipped with12 megapixel lens, 28 mm and f 1.8,12 megapixel lens, but 56 mm and f2.8

Apple compared the 56 mm lens in the iPhone 7 Plus to a "telephoto lens". But in fact, it is far from the telephoto, and the magnification is twice that of the 28 mm lens. This 56 mm lens can help you avoid the common photo distortion problems when taking portraits and other photos.

Apple's attention to the iPhone 7 Plus is a bit vague. The configuration list does not say "2x optical zoom", but "2x optical zoom". This small difference may not be noticed by many people. Technically, this system can achieve double zoom, because you have a 28 mm lens and a 56 mm lens, which means that two different lenses can zoom. Zooming, as the name implies, means that the focus moves from one point to another, so for Apple's "2x" statement, we can only understand that when the 28 mm lens zooms farthest, the 56 mm lens can take over the zoom task, which is like doubling the overall zoom capability.

If the second lens is 70 mm instead of 56 mm, then this is actually no longer an optical zoom. This situation should be called bifocal. Through the corresponding algorithm, the multi-camera system can focus between the focal lengths of two lenses. Apple just switched from the first lens to the second lens, and then called it "2x zoom".

JPEG photos you take with iPhone will be automatically compressed and processed. This kind of lossy compression will reduce the number of colors in the photo and the fidelity of bright and dark areas. This is easy to aggravate the trace of the photo being p when editing the picture later.

Raw images directly store the data received from the lens, so you won't let the traces of manual modification become more and more obvious when editing. The reality is that even if you can edit Raw pictures, the range of data you collect from such a small shot is limited, so adjust the exposure and noise anyway. It's true that you can manipulate all the data collected by the lens, but the problem is that the lens is really too big, and it doesn't collect many colors by itself.

Question 8: How to use the Apple 7plus dual camera automatically? No setting is required. Dual cameras will better reflect the depth of the picture.

Question 9: How is the dual camera of Apple 7plus set to use only one lens? Only one camera is used, one is wide-angle and the other is telephoto. What focal length is used?

Question10: How to use the dual camera of iPhone 7 Plus? You should know that one of the 7p dual cameras is specially focused and can be magnified many times. You just take pictures normally.

In addition, there is a new function, Live Photo, which allows you to see the dynamic effect of photos taken through 3d touch.
