@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 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 😅
@AudeCaussarieu Je me demande quand même à quel point c’est difficile de distinguer de telles anomalies de distorsions optiques causées par la lentille, qui va courber les lignes parallèles.
@grototo @AudeCaussarieu On verrait un autre genre de déformation, pas des trucs au pif comme ça, je dirais ? De toute façon dans le genre de photo montré est rarement prise en grand angle...
@legendarybassoon @grototo @AudeCaussarieu
Oui, je suppose ça ferait une forme pas exacte, mais pas random.
L'images des cubes par exemple, il y aurait de la symétrie, pas juste un des points qui va n'importe où.
Et j'imagine la gueule des prompts pour dire de se concentrer sur les points de fuite, difficile à décrire en langage "naturel". Avec un peu de chances ça va pas être facile à corriger.
@AudeCaussarieu
J'aurais jamais pensé que les points de fuites pouvaient être une façon de vérifier la véracité d'une image. 🤯
