Automatically P texture and details when taking pictures of the moon with mobile phones: What will AI add to the photos?
In 2023, Ren Ng, a computer professor and computational photography course professor at the University of California, Berkeley, said that as we move towards the future (AI photo editing), photos are no longer just "visual facts" . Now, not only can you input a prompt or two into a generative image-based AI like Midjourney, it will generate a picture that looks almost real. Smartphones have actually added AI technology to their cameras for a long time, and can even directly intervene in your photo shooting.
In 2021, a hot post on the reddit platform triggered a discussion on "automatic forgery of mobile phone photos".
- Cause: Someone downloaded a clear photo of the moon from the Internet and blurred it to erase the details.
- Place it on the computer screen to create a blurry "fake moon".
- Photograph the fake moon with your smartphone.
- The phone’s AI recognizes the fake moon and adds details to the photos taken, giving the illusion of clarity.
This suggests that the phone’s AI may be “beautifying” the photo rather than providing true clarity.
If you want to fake it, you need AI to first recognize that the "ball" in the photo is the moon, and then paste the fake moon on it to make it look real.
A foreign media once reported that computer experts found in subsequent tests that this smartphone does not deceive people in this way, and there is no such design in the program code. In other words, it won't put fake things directly on top of real photos.
However, the AI algorithm built into the mobile phone interferes with photos more and more complexly than we imagine.
In this mobile phone that claims to have a powerful zoom photography function, the spokesperson explained that AI may recognize the specific scene you shot when previewing it in the phone’s photo frame, and then when shooting, the AI image processing function will “ Continuously adjust between "realism" and "details" to piece together high-quality images. In this process, no fake photos were added, but AI participated in fixing, stabilizing, focusing and adjusting thousands of times. (Already dizzy...)
1. The Verge believes that the authenticity of photos is not opposites, but two ends of the spectrum.
2. Smartphone photos are optical + AI calculation data, and the degree of adjustment is a matter of opinion.
3. What users get by modifying details is the photo they want, which may not be true.
4. For the first time, Google Pixel 8 brings generative AI to mobile photography, which can enhance photos by, for example, removing passers-by, clutter, or generating pets.
However, sometimes this can also become a criticized function. Some people have discovered that some mobile phones will automatically process the photos taken, making them unrealistic like "watercolor paintings".
Vlogger Marques Brownlee once complained that the iPhone would add a lot of strange artifacts to photos in low-light environments. On the Apple community, someone discovered that this does not seem to be a function of the camera APP, but the automatic AI processing function of the mobile photo album.
If you don’t want these features, you can directly turn off the AI function, or turn off the automatic photo optimization or HDR function. Powerful AI functions are sometimes what we need, but they may also cause trouble. Nowadays, it seems that everyone can be a photographer, but the advancement of photography technology may force us to welcome a new future, where what you see is not necessarily what you get. A photo may have been processed by AI and changed by an algorithm.
