They’re all AI because whatever phone took those pictures has AI upscaling

Assuming some are real and some are fake, my bet is 1 and 3 are fake.

AI, those trees have too many fingers…

Nature shots have been cheating for a while, because most errors are still plausible.

The major tell is how screen-space anything is. In real life, there’s very few angles where the top of a close thing stops at the bottom of a far thing… but neural networks aren’t modeling depth. Probably. So things are tangent or coincident all the dang time. Even in the patterns of grass and brush and whatnot, where the network does T-junction patterns like brickwork or cracked pottery, when it should be closer to woven or thatched.

1,3 and 5. They have that weird pattern in the grass and trees. However, it’s getting close. I think soon most people would never be able to tell.

1. Fake

2 . Real 3. Fake 4. Real 5. Fake 6. Real

Are AI images I’m pretty sure, a lot of odd hashing of lines in some of those distant trees.

1, 3, 5 are all fake. Rest are real, including 0.

You gonna tell us the answer?

I agree with many others, 1, 3, 5 look most suspicious (assuming numbers precede pictures)

Others seem to have heavy upscaling but it doesn’t tend to become too patterned. In 1, 3, 5 grass tends to become something like a fractal rather than grass, plus reflections are sometimes off (that is why 2 is a bit suspicious because of a small tree reflection, but maybe it’s just hard to see the original tree), and the branches tend to grow from multiple trees at the same time

With the HDR effect added to these it’s honestly difficult to tell which are generations and which are just heavily post processed

5 is the only one that looks real to me.

I guess 5 and 6 are real

The only one that looks like AI to me is 2

My guess is they’re all real except #5. That one doesn’t have as many good reflections off the water.
