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.

In other words, they were shot on an iPhone. And processed there too, incidentally. 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.

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.

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.

I see zero evidence of an effect like that in the linked photos. I assumed they were talking about artifacting they saw in their own attempt to take photos at night with an iPhone.

Either way, given the content of those links, I don't think their comment makes much sense.

Uh, yeah, that’s standard process for astrophotography. Not at all a “c’mon” moment.

It’s still extremely impressive that a smartphone camera can do this. I say this as someone that does a good bit of astrophotography as a hobby.
