    Some phones just insert stock photos

        Samsung GS22+ owner here. I’ve watched in realtime as a blurry blob moon photo I just took was replaced with a clean recognizable “moon” in my gallery, a few seconds after taking it.

        It wouldn’t surprise me at all if this has gotten more advanced in recent years. Identify a few key stars as reference, and then paint in a pretty Milky Way from pre-defined images, while pretending to collect a timelapse.

          It’s called post processing. Generally it takes multiple frames and combines them or gets other camera data.

          In theory, if this were true, you should be able to get a light, place it where the moon is and point it at it, and it should replace it with a moon. But it doesn’t.

            Im familiar with post processing.

            To be clear, the assumption is that the algorithms the phone is using to determine you were trying to take a photo of the moon are “smart” enough to identify it as a photo of a night sky focused on the moon, rather than a light bulb. I’m not sure how you’d set up a light of the correct brightness at infinite focal length to test this though.

            ETA: I’ve never seen this post processing happen so starkly with anything other than a photo of the moon, so it sticks out pretty hard. And I take a lot of photos at work of things that are tough to capture clearly.

            I had to dig through my phone to find these photos when i got home from work, but they were taken literally seconds apart with my phone on full optical + digital zoom. The detail on the second is absolutely absurd, while the first is what I typically see on my screen when I’ve tried to replicate since.

              I reckon it’s just processing a raw capture. The only difference is exposure, which yeah, phones could easily post process.
