The user downloaded a high-resolution photo of the moon from the internet, downsized it to 170x170 pixels, applied a gaussian blur to remove all details, and then displayed the image on a monitor at full screen (still showing it at 170x170 pixels and blurred). They then moved to the other end of the room and turned off all the lights before photographing the moon using Samsung's space zoom feature.
The user asserts that Samsung uses an AI model to add craters and other details to previously blurry areas. They differentiate between additional processing, such as super-resolution, where multiple frames are combined to recover lost points and the AI model used by Samsung, which recognizes the moon and applies the moon texture to it when there is no detail to recover in the first place.
The user concludes that moon pictures from Samsung are fake and that Samsung's marketing is deceptive because it's the AI doing most of the work, not the optics. The optics cannot resolve the detail you see, and since the moon is tidally locked to the Earth, it's easy to train the AI model on other moon images and apply that texture when a moon-like object is detected.
