I may not have turned on the professional mode of taking photos on my mobile phone for three years. This function used to be very exciting. By adjusting a few English parameters, just like a butterfly flapping its wings to cause a storm, the whole picture will be different. < / P > < p > speaking of the professional mode of smartphone photography, we have to mention Nokia, once the king of mobile phone photography. Nokia’s rise in photography has largely started with the Nokia N8 and peaked at the time of the Nokia 808 and lumia 1020. < / P > < p > a long time ago, when Nokia was still in the ascendant, powerful photo taking was just a icing on the cake function. In fact, Nokia N95 and N82 were definitely high-quality mobile phones in those years, but the importance of taking photos did not catch up. That is, after the rise of mobile Internet, social networks gave rise to more demand for taking photos. < / P > < p > in the era of Windows Phone, as the most vulnerable party among the three forces of smart phones, Nokia’s lumia series has to rely on photography as the biggest selling point of mobile phones. In addition to today’s view is still the bottom of the CMOS, professional model has been amazing for a time. < / P > < p > in the camera applications updated in 2013, Nokia has loaded professional mode into lumia series mobile phones. The interactive interface and rich manual adjustment functions are still benchmark design today. < / P > < p > but this situation did not last long, or people underestimated the development speed of mobile phone automatic mode. After some conceptual bombardment such as “mobile phones that can shoot stars”, the pixel generation released in October 2016 opened a big chapter in mobile computing photography, and the professional model can only be in a corner. < / P > < p > think carefully, in fact, the professional mode is gradually ignored, which is closely related to the greatly enhanced availability of mobile phone automatic mode and the rapid development of computational photography behind it. < / P > < p > the most common way to use professional mode is to adjust the shutter speed, exposure and ISO to make the picture not exposed but also dark, or long exposure to achieve fun effects such as light band. < / P > < p > but with the development of mobile photography, these functions which originally need professional mode, and even can only be realized in the later stage of computer, are gradually separated from each other. Night scene mode, HDR, streamer shutter, and even the simulation of large aperture which can not be realized by professional mode have become the selling points of one press conference, and they are slapping hands on the face of professional mode. < / P > < p > the effect of automatic mode is getting better and better, and the demand for professional mode will be less and less. But what I want to say is that after AI lowers the threshold of taking photos, it actually makes the threshold of professional mode relatively higher. < / P > < p > for example, if the brightness of the picture in automatic mode was too dim in dark light, some users with experience in camera use may switch to professional mode, reduce the shutter time, improve ISO, and try to make the hand hold more stable. Finally, after several attempts, they can get a photo that balances the brightness, quality and film yield. < / P > < p > or in the setting sun, when you want to create a silhouette photo of an overpass and a pedestrian in the backlight, the automatic mode will automatically turn on the HDR function. Even now, the HDR of many mobile phones has been too hard, and it is determined that they can not take the photos they want. < / P > < p > it’s time for professional mode to play a role. Reduce ISO and increase the shutter speed to suppress the light outside the sunset background, so that you can easily get a silhouette photo you want. Although the ability of manual adjustment of the camera is not related to the ability of manual adjustment of the camera, it also has a lot to do with the quality of the camera.
but now the AI machine learning is very influential between creators and mobile phone. AI performance is very unstable, which makes the relationship between the three more complex. You want to get the best, but you can use automatic mode to hand over to the machine, or use professional mode to shut it out. < / P > < p > inappropriate HDR and multi frame synthesis can easily make the picture blurred or flattened and lose the sense of space. The highlight, which has been valued by a large number of netizens, can easily turn the original white light blue when it is too hard. At the same time, the light emitted from the lamp box will lose the sense of volume. The light seems to be compressed into a piece of paper, which is very strange. < / P > < p > at the Xining first Youth Film Festival, I also asked Li Zhuo, the video director of vivo, a question about AI and creation, and got a positive reply. Under the popularity of various AI enhancements, it is actually a kind of harm to the creators. The stable effect and colorful pictures after beautification may not be what the creators want. < / P > < p > but when you switch to the professional mode of losing the bonus of computational photography, the hard quality of mobile phone photography itself will be exposed. If you want to create some themes, you will find that the image quality will decline greatly after losing the AI blessing, even the lens will not be stable enough, and the color will also be lost. < / P > < p > you have to think about whether you can take more photos, go back to the PS manually stack, and then do a lot of later work to repair the effect you want. Can think like this, the hand of the camera emperor seems to be suddenly not fragrant. < / P > < p > maybe manufacturers should have a good look and learn. To what extent have professional third-party camera applications evolved? They simulate log mode video, provide many algorithm generated simulation style filters, and rich manual settings, there are also positive uses brought by machine learning. < / P > < p > it is undeniable that the difference between the automatic mode and the professional mode is becoming bigger and bigger. If the professional mode could be played only with a little experience in camera use, now it needs not only experience, but also excellent post-processing technology. For a large number of people who are not full of “professional” above “Xiaobai”, the professional mode has become absolute It’s tasteless to eat, but it’s a pity to cut it off. < / P > < p > some people may think that it is a good thing that this widening difference will make the public and professional or semi professional creators more clear. Everyone can take what they need. Even your professional and semi professional people will play with the camera and don’t touch the mobile phone. < / P > < p > but I don’t think so, because it is actually negating the value of the professional model, and I think its existence is valuable. If the utilization rate of the professional mode is getting lower and lower, it is not that it should disappear, but that the current form is not good enough. < / P > < p > for the professional mode, we always have a view that it should be the product of stripping AI and computing photography. It seems that all the will that does not belong to human should be pressed to death. But in fact, this is not a good professional model, or an outdated definition of professional model. < / P > < p > why, although pixel series mobile phones are relatively backward in terms of CMOS and multi camera solutions, a large number of users at home and abroad still think that their photo taking ability is very outstanding, that is, their powerful computational photography ability is constantly correcting the picture performance. < / P > < p > in this era, it is impossible for us to completely eliminate the influence of computational photography. Moreover, the future development trend is that computational photography will be more involved in imaging. < / P > < p > when computational photography becomes the underlying algorithm, we should not deprive this part of the image enhancement, even if many machine learning algorithms do not affect the creative expression of personal will. < p > < p > for example, super-resolution algorithm is a set of commonly used algorithms for high-power zoom of mobile phones. It is a set of effective image quality improvement algorithm after a lot of neural network training. This is obviously a part of computational photography, but it will not affect the creative expression of users except for the improvement of image quality. < / P > < p > we should get rid of the misunderstanding in the past. The significance of professional mode is never to raise the threshold, but to enable users to express their creation in the most appropriate way. In this regard, manufacturers should actively further optimize the usability of professional models and further reduce the threshold of their use through reasonable ways. < / P > < p > let people decide whether AI is involved or not and which link is involved. The more we understand how machine learning works, we can know how to better use it. Maybe this is a better and more advanced professional mode.
