A few days ago, I pulled out an iPhone 3GS from the corner of the drawer. After charging, the familiar Apple logo turned on. With the long lost “click” unlocking sound, the phone, which has long been history, has come back to life in my hand. < p > < p > on the last day of October 2009, there was a huge crowd in front of the apple store in Sanlitun, Beijing. Fruit fans from all over the country gathered together to welcome the special moment when the iPhone officially entered the Chinese market because of the first sale activity of the Bank of China. The models on sale on that day were iPhone 3G and iPhone 3GS. Ten years later, Apple’s iPhone 11 series, launched last year, has become an “arcade”, and the hardware configuration and software functions of the new device are no longer the same. If we put together two iPhones that are 10 years apart, maybe we can see more clearly the progress of the iPhone in this decade. < p > < p > of course, the texture of the iPhone 3GS plastic body is superior to that of the iPhone 11 pro’s glass body + stainless steel middle frame. Although the latter is larger and heavier, and it is not easy to operate with one hand, the texture of the whole machine is a “qualitative leap” compared with ten years ago. < / P > < p > the first generation of iPhone 2G and the second generation of iPhone 3G only have the ability to take 1.2 million pixel still photos, while the iPhone 3GS has been upgraded to 3.2 million, and the functions of video capture and auto focus are added. However, these configurations are still “insufficient” in front of the iPhone 11 Pro released last year. Let’s take a look at the following sample comparison: < / P > < p > iPhone 3GS The 3.2 megapixel front view image sensor from omnivision is adopted. It supports auto focus, video capture and other functions for the first time, which is much better than the first and second generation iPhones. < / P > < p > we can see that even in the scene with sufficient light, the impression of the photos taken by iPhone 3GS is still full of “sense of age”. In addition, due to the inherent defects such as low pixels and no support for HDR, once there is a large light ratio in the picture, there will be short boards with high light pressure and loss of dark details. In addition, the picture is much narrower than the main camera of iPhone 11 pro with equivalent focal length of 26mm. < / P > < p > looking at the iPhone 11 pro on the right, thanks to the hardware advantages of higher pixels and optical anti shake, as well as the optimization of intelligent HDR and AI software, the overall impression of the photo is even better than that of some entry-level SLR / card machines. < / P > < p > if the light environment is a little worse, you may face the embarrassment that you can’t record the picture at all, and you will be waiting for a nearly black photo. After all, the iPhone 3GS does not support the so-called “night mode”, and there is no flash to fill in the light. What you can take at night depends on the “Providence”. < / P > < p > however, the upper and lower limits of the recording ability of the iPhone 11 Pro are higher. Some scenes full of noise after being shot by the iPhone 3GS become more pure. Even in the scene with almost no natural light source, the iPhone 11 Pro can record by relying on the software optimization of “night mode”. No more, there is a rear flash lamp that can serve as a light supplement. < / P > < p > as the “end point” of quasi materialization, we are used to flattening and then look back at IOS 6 There are some regrets, such as the classic sliding unlock sound effect, the rolling shutter animation of opening the camera, etc. Although many software and functions are still immature, the status of quasi materialization is still unshakable in the hearts of many fruit fans. After all, the fun we get from small games such as angry birds, fruit ninja and graffiti jump is fast-paced now Online games can not be replaced. < p > < p > ten years is an imprint, a summary of the past and a vision for the future. Although the equipment that used to accompany us is old and out of repair, and we have been replacing it with new equipment year after year, memories other than hardware equipment may be more valuable.
