And yet you can’t take a picture of the stars or street lights on an iphone…

Physics is still the law. As long as your aperture is small, so is the usable amount of light you’re collecting at the top of that lens funnel.

  The problem is that the tiny light from a star or from a street lamp post is multiplied (in software) multiple times to a comic effect...

Is this just a software problem? Android has had various night sight modes for several years that make dark views work pretty well?

  There is something with the hardware as well, there is some green glare even on easy shots, but the fake lights problem I think is software, the software tries to "pretty" the image and introduces these fake lights.

  C'mon. From your link: "The images were shot using Apple's ProRAW format and then edited using the mobile version of Lightroom on the iPhone itself" I have the 12 and it multiplies any tiny source of light in dozens of fake lights. The street light I;m referring too is much darker than this: a dark street with a string of lights. All the lights will get multiplied as fake lights.

    > The images were shot using Apple's ProRAW format and then edited using the mobile version of Lightroom on the iPhone itself In other words, they were shot on an iPhone. And processed there too, incidentally. What's to "c'mon" about?

      > What's to "c'mon" about? Maybe the fact that there are many artificial stars in that photo due to software adding new light sources which didn't really exist in postprocessing? I have no idea if this happens but it is the claim they were making, and would certainly be worthy of a "c'mon" if true.

        > Maybe the fact that there are many artificial stars in that photo due to software adding new light sources which didn't really exist Huh?? How exactly did you come to the conclusion they just added a bunch of fake stars? Am I missing something? Post processing is a normal part of astrophotography, even with a DSLR.

        That sounds like a question for them, not me, I made no such claims. In fact I'd be quite interested in any evidence as well, although I wouldn't be surprised if they were using some kind of ML model in postprocessing which ended up adding some extra stars here and there (more charitably, you could think of it as converting noise into stars, when it was really just noise all along). But I'm certainly no expert on how smartphones process their photos. > Post processing is a normal part of astrophotography, even with a DSLR. Yes as someone interested in low light photography I'm well aware of this and it's why I'd be quite curious to see any evidence (assuming it exists) of smartphones doing weird things to their low light photos.

Of course you can. Stars example: https://www.macrumors.com/2021/10/10/amazing-night-sky-photos-iphone-13-pro-max/ https://www.macrumors.com/2021/10/10/amazing-night-sky-photo...

    Do you have an example for that? Would be interesting to see. Edit: Or do you mean lens flaring like here? https://discussions.apple.com/thread/252037681 https://discussions.apple.com/thread/252037681
