@FabMusacchio I don't know, I've seen some pretty bad tile jobs :)

oh this is a neat trick, I usually look for distorted writing and other small detail, but latest AI models are getting better at those

@FabMusacchio Also, what's with the chains? And look at the left thumb on front and center guy.

@FabMusacchio I would be more tolerant in the first example with the soldiers, because many builldings are not build perfectly straight or remain like that. If there is only a small error, it would not be a strong indicator for a fake. Of course, this doesn't apply to the other examples.

@FabMusacchio Someone should do this with moon landing videos

@FabMusacchio Perhaps they came to arrest the tiler?

@FabMusacchio damn, this is why they taught us math? To find the deep fakes posing as truth?

@FabMusacchio in the first picture, the lines may be off by measurements inaccuracies. a mirror image depends on a perfect mirror on the physical mirror. and the shadows may be off by camera lens distortion.

@FabMusacchio Flat-earthers will not understand this

@FabMusacchio @peterdrake In so-called AI-generated or OCR-based image descriptions, AI is often spelled Al.

@FabMusacchio soldier faces behind front ones are melting as well. But this is more scientific approach and will work all the time

@FabMusacchio In the third photo, the second paragraph of added text contradicts the first paragraph. (The first paragraph is correct, and the second is false. What is wrong is not a slightly inconsistent vanishing point, it is that the shadows are at visibly different angles in the first place. There should be no measurable vanishing point at all.)

@FabMusacchio Another group of lines I often follow is from the knees, and from the backbone/visible parts of hip, towards the hip joints.
Years of anatomical drawing lessons paying of.

@FabMusacchio so basically you can determine if an image is a fake using parallel lines

@FabMusacchio Plus, in the first photo, those lines of "moving" soldiers are just a little too perfect. Nobody can march in formation without *some* deviation.

@FabMusacchio What is wild to me is that any photoshopper worth their salt in 2005 wouldn't have screwed the lighting or reflections up.

@FabMusacchio

Good points… except the bad one: the dinosaur graphic shows a line connecting different toes to the horizon

@FabMusacchio in the soldiers pictures… there are like a hundred giveaways that it's fake easier to spot than the sligthly off parallel line.

nothing makes sens. the chains ?? so much to say about them. Why ? where are they attached ? Why are they so unconsistent ?

The uniforms that are not uniform. like. You had one job. The helmets… the nonesense "text". the collars. the trousers too large ? In the military ? I don't buy it. the shirt that looks heavy and "cargo" at the top bit they look light like an everyday summer shirt painted green. And what are those white dots ? The masks, what... what are are they ? are they masks or chinstrap ? and what do they seam to eat them, are they nervous ? They you look at the figures behind and find that they make less and less sens at each row. they sort of melt.
And The guns. what are they. you can't even identify each parts of the weapon. and then you look a the hands. why are they blended ?

and. look between the legs of the front figure. it like there are no one behind him.

I could go on all day about so many obvious mistakes.

It feels like an "early" Dall•e picture the way it kind of seems painted and blended.

@FabMusacchio defeated by simple trigonometry. nice.

@FabMusacchio especially with the first image the building might be a bit crooked or the lines might just be a bit off. It's pretty close to having a vanishing point. It's even closer to having a vanishing point if you remove the wall line, that might not be perfectly parallel and look just at the tiles.

@FabMusacchio thanks for reposting, these are great tips to help spot fakes:) it's getting incredibly hard, if not impossible lately: (

@FabMusacchio Great to have a sure way to prove things, but honestly, just zoom in on details see if they're coherent? In most if not any genai image? Not even talking about the dinausore/crocodile one because if you're under 50 you could tell in one blink

@FabMusacchio good post 👍

@FabMusacchio Hello! Can I ask where the url shortener sends?

@FabMusacchio it is really telling that one of the most powerful tools to detect fake images is an artistic tool that any first year art school student knows about

@FabMusacchio beautiful analysis.

@FabMusacchio So if I want to commit a murder, I have years to prepare it and I know the place will be surveilled with cameras, I should pave it with slightly non-parallell tiles, to get a plausible deniability.

@FabMusacchio Interesting. Thanks for posting!

@FabMusacchio How does this method handle lens distortion?

@FabMusacchio
Very interesting, thanks.
@defakator it might be of your interest?

Ah bah voilà une super source d'exos d'optique géométrique 😅
