In the field of mobile photography, new technologies and features are emerging one after another. Take the "flash shooting" function of the recently high-profile Huawei Pura70 series as an example, which is undoubtedly a striking technological innovation.
At first, you may think that this is just another marketing gimmick launched by manufacturers to attract consumers. However, far from the truth, the technology behind this feature is quite high and should not be underestimated.
Maybe some of you haven't experienced the flash shooting function of Pura70, so please allow me to give you a brief introduction. With this feature, your phone can capture images of objects moving at speeds of up to 300 km/h without any afterimages.
Whether it's a speeding race car, a kid riding a bicycle at home, or a high-speed train roaring by, all the dynamic scenes can be clearly recorded.
If you doubt this, you might as well take a look at a video of the CD drive officially released by Huawei. The video shows the high-speed rotating optical drive, captured in full and clearly, which is the strongest proof of this. If you change to a regular smartphone, you may only be able to shoot a blurry image.
However, this naturally aroused doubts and doubts among netizens. Some people have suggested that Nokia's old phones can easily shoot high-speed rotating fans, and Huawei can show off this again?
If you think about it carefully, everyone's doubts are reasonable. After all, Nokia used to solve the problem of shooting high-speed objects by increasing the shutter speed. The faster the shutter speed, the easier it is for fast-moving objects to be "frozen" in the frame, which is the basic principle of photography.
So one wonders why modern smartphones are so hard to do this? Is it really as some people say, the technical level of today's flagship mobile phones is not as good as the old mobile phones more than ten years ago?
In the face of these doubts, I really felt a little crying and laughing. In fact, modern mobile phones are fully capable of shooting high-speed moving objects by increasing the shutter speed. However, manufacturers are not taking this approach, but there are deeper reasons.
While increasing the shutter speed allows you to capture moving objects, it also introduces another serious problem – increased noise, loss of detail, and color distortion that can lead to a significant loss of photo quality and feel.
Imagine spending a few thousand dollars on a flagship phone with great pixels, but it doesn't shoot as well as it did a decade ago?
The reason for this is that the shorter the exposure time, the less time the sensor has to receive light, and the completeness of the information collection is naturally reduced.
At least in the past, older phones faced the dilemma of limited hardware configuration and insufficient algorithm power when taking photos. As a result, they can only solve the basic problem of "photographing clear objects" first.
For mobile phones of the day, maintaining a high shutter speed was the minimum requirement, otherwise the captured image would be blurry. However, today's phones already have excellent hardware and algorithmic capabilities that can strike a balance between the two, without having to rely on the old-fashioned method of increasing the shutter speed. That's the crux of the matter.
When you're still concerned about whether your phone can shoot a clear fan, you may have overlooked the leading technical prowess of the Huawei Pura70 series. One of the highlights of this model is that the core of the "Flash" feature is not just about increasing the shutter speed.
It uses innovative dual exposure technology and an AI-based approach to computational photography. Each time you take a photo, the camera makes a short and long exposure. A short exposure is used to capture details of a moving object, while a long exposure is used to capture background environmental information.
Next is Huawei's housekeeping skill: through AI algorithms, these two photos with different exposures are intelligently fused. This not only preserves the details of the moving object to the greatest extent, but also restores the rich layers of the background. The result is a high-quality, detailed, moving photo.
This method is nothing less than a finishing touch, so that objects moving at high speed can not only be photographed, but also photographed with excellent results. Users no longer need to sacrifice most of the image quality for the sake of capture, as they did before. Whether it's the user interface, the details or the color reproduction, the Pura70 series performs very well.
To achieve all this, there is no doubt that the hardware performance, computing power and algorithm level of the Pura 70 series mobile phones have put forward extremely high requirements. Nokia's older phones couldn't do that, because they just stuck on a very rudimentary, clunky solution.
At the same time, Huawei's method of operation also abandons the outdated concept of "shoot first and then speak". Huawei's goal is to seamlessly capture the details of high-speed objects while providing a superior image quality experience.
Therefore, if someone says that a certain Nokia mobile phone more than ten years ago can kill the current flagship model in seconds, this is actually a complete joke.
With the rapid development of mobile phone technology and the continuous innovation of manufacturers, breakthrough technological innovations like Huawei, although it may be questioned and criticized in the short term, will undoubtedly be regarded as an important milestone in the development of the industry.
Looking to the future, there may be more mobile phones that take a similar technological route, as consumers' pursuit of a photographic experience is never-ending. However, if any manufacturers continue to rest on their laurels and use outdated and low-grade filming techniques to entertain consumers, they will sooner or later be eliminated by this wave of technological advancement.
Therefore, we should maintain basic common sense and an open and inclusive mind. For new things, we should maintain rational cognition and patient observation, and not be confused by superficial phenomena. Science and technology are constantly evolving, and we must also keep pace with the times, keep up with the pace of the times, and enjoy the new experience brought by new technologies.
