Show HN: AI-generated images that look like real life
- spaceman_2020 2y agoso a few days back, I discovered that with the new Flux v1.1 pro image gen model, if you use a prompt like "IMG_XXXX.HEIC", you get some extremely realistic images. I spent a few hours playing around with it, trying out a ton of combinations. Ended up with a very large library of images and decided to make a quick website to share it. Some notes and observations: 1. Using a prompt like "IMG_XXXX.HEIC" tends to yield the most realistic images, but most of these tend to be rather mundane images of landscapes, flowers, poorly shot cityscapes 2. Adding "IMG_XXXX.HEIC posted on Snapchat in [year]" yields more realistic, casual images of people. However, a lot of these look like screenshots, complete with the Snapchat UI. Most people also tend to be attractive. 3. Adding a [year] in the prompt yields some interesting images. Like [2017] will yield blurrier images than [2023]. Adding [2021] in the prompt got images with face masks and face shields 4. The prompt "[firstName] [lastName] selfie" gets real-looking selfies of real-looking people. You can use Indian, Hispanic, Chinese, European, American, etc. names and get realistic images of people with these ethnicities. Example: https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/pc5JnhNRUEqu4FMSBbhA4.jpg https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/pc5JnhNRUEq... 5. There is a decently high failure rate. The ~750 images on the site are hand picked. I had to delete around 220 images for not meeting the criteria (not real enough) or being just bizarre 6. If this model is any indication, its soon going to be impossible to tell what's real online
- puttycat 2y agoGiven your technique, how can one verify these aren't just copies of the training data?
- WithinReason 2y agothe model is too small to memorise that much, and papers usually check things like "closest sample from training set" so we know it's not memorising (unless it's an image that's hundreds of times in the training set like the Mona Lisa)
- puttycat 2y agoHow do you quantify "by that much"? It can memorize at least some of the images for sure. Potentially these are the images OP was able to recover.
- WithinReason 2y agoWhy would it memorize some but not others if each contributes the same amount of information? E.g. the LAION dataset is about 240TB, while FLUX is about 10GB, so it could only memorize 0.00833333% of each image, not enough to reproduce it.
- DougN7 2y agoI had the exact same question.
- joegibbs 2y agoWow that's amazing, you really can't tell. What is it that gives most AI images that not-quite-real look? Is it due to airbrushed images in the training data, including cartoons, 3D renders and illustrations or all of that?
- Hasnep 2y agoThe image linked in that comment has a background that's half car and half building, but yeah apart from that minor detail it's pretty hard to tell.
- pepa65 2y agoI was going to say that. Pretty crazy! The seatbelt looks more like a robotic arm. Yet at the back there is a curve and a back window. It's really a hybrid car-building. Wondering what the black bar at the top is about...
- mkl 2y agoMost of these look very good! Signs, text, clocks, number plates, and girders or spindly branches tend to go wrong. There are a few mutant hands [0]. Mountain Sheep in Snow [1] looks fake to me - the sheep are more like dogs fading back to rocks, and have different scales. Underground Time Display [2] looks obviously fake as the clock's colon is in the wrong place and the sign has fake writing.

- madamelic 2y agoI wonder how far into generative AI will have people developing "intractable FOMO" where they see a beautiful place but then they find out they can't visit it because it doesn't exist. Are we seeing it already from people who are getting irrationally angry about generative AI?
- spaceman_2020 2y agoHonestly the output from this model was a little scary. I could always tell AI generated people and images prior to this But most of the images here are just mundane enough that they could have been taken by your average smartphone user
- mattgreenrocks 2y agoI definitely can’t tell, even knowing that these are from AI. GeoGuessr-like sites are going to get trolled hard with AI photos of nonexistent locations.
- _sys49152 2y agocityscapes and urban photography - only a handful of examples given but those images still got a ways to go
- slau 2y agoA bunch of the people images are very clearly AI though. I’d wager about 30-50% of them could be recognised as generated by people with a bit of understanding of how these models work.
- ninetyninenine 2y agonobody knows how these models work. Not even experts. These are black box algorithms where people understand these things in terms the analogy of a best fit curve in a series of data points. Outside of this analogy... nobody understands how generative AI works. What made a model for a specific situation choose to generate a hand with 6 fingers instead of 5? Or 5 instead of 6? Nobody knows.
- sync 2y agoGreat work! I think you have a business similar to Lummi[0] if you: - Enhance search capabilities - Add a paid API - Add a whole lot more images :) Other royalty free image APIs out there like Unsplash[1] have difficult licensing terms. AI is poised to disrupt this space. [0]: https://www.lummi.ai https://www.lummi.ai [1]: https://unsplash.com/developers https://unsplash.com/developers
- 1024core 2y agoThrow these into a captioning system to generate captions, index those captions with something like ElasticSearch and voila!
- bentocorp 2y agoUntil AI generated imagery has been tested by the legal system it may be a bit too optimistic to call this "Royalty-free, copyright-free gallery of images". How different from a source image do these AI generated images need to be to be considered "copyright free"? If I grab a series of photos from shutterstock, run them through a generative AI photo enhance process to improve the white balance, contrast and levels is that adequate enough to be considered "copyright free"?
- ninetyninenine 2y ago>If I grab a series of photos from shutterstock, run them through a generative AI photo enhance process to improve the white balance, contrast and levels is that adequate enough to be considered "copyright free"? Hard to say. If I had the generative AI copy the photo but change the time of day and angle then would it be copying? What if I went to the same location and changed the angle and the time of day? Would that be copying? AI is essentially "drawing" the same photo from a different time and angle. What if I did the same thing photorealistic-ally by hand in photoshop? Would I be copying if I painted the picture in the same way the AI did it?? I want you to consider what I'm doing here with my reply. I am admitting to a crime right now. What I have done with this reply is literally rip off different vocabulary words and certain short phrases from books all over the world and mixed up those words and phrases to produce the reply here. I am ADMITTING to copying those books. You going to accuse me of a crime even if I admitted to it? No. But if I did the same thing with AI.... you going to accuse me then?
- amelius 2y agoYour argument is based on a series of slippery slopes that I'm sure a judge would not tread on.
- ninetyninenine 2y agoI didn't even make an argument. I'm saying it's not clear cut.
- jessriedel 2y ago
- 7874cole 2y agoYour website is loading forever, is it down?
- mrtksn 2y agoThe vibe I'm getting, they try to make it look real by making it dull. The problem with AI images is that they don't make sense and by making the image dull, it reduces the urge to make sense of it I guess. AI images have very low fidelity. You know the "A picture is worth a thousand words" phrase? I think AI images fail on that because they are not an instance of a very complex system but a very concentrated subject if you know what i mean. When someone captures a picture of a dog, that's actually a picture of a story about the past; That is, the surrounding environment is arranged in a way that you can tell what just happened moments ago or years ago. AI Pictures lack that story and that's why I think the dull images are easier to pass as real because they don't induce you to think about the moments ago.
- Retr0id 2y agoAI-generated images aren't worth a thousand words, at least for now, because the "prompt space" is just too small.
- mmastrac 2y agoThis trick has been floating around for about a week -- earliest ref I could find: https://x.com/fofrAI/status/1841854401717403944 https://x.com/fofrAI/status/1841854401717403944
- lsy 2y agoI guess the question is: Who cares? What is this for, except illustrating blogspam? It seems that more resources are being poured into verisimilitude across generative models, but what is the business model or even human use case for it? A picture of a glorious landscape seems worthless to me without any grounding to be able to ask a question like, "where is that?", "when do those flowers bloom?", "what is on the other side of that mountain?" and receive any kind of interesting answer.
- elicksaur 2y ago1. Scams. Human deepfakes/fake-fakes to make you believe you’re communicating with a real person. 2. Self-image editing. You want a picture of yourself doing something you are unable to do. Could be benign, but very likely being used as a scam on social media in some way. 3. Marketing. Putting your product in some setting without having to do a photoshoot. People will argue this isn’t a form of scam, but it seems suspect to me.
- netsharc 2y agoCan't wait for an influencer that has thousands of travel pics, thousands of likes and comments, but they're all computer-generated. And then for the influencer to try to get freebies from companies in return for a favorable review in her feed. Also, asking AI for a generic image is a lot cheaper than paying for stock photos (do stock photo services still charge buyers a lot and pay photographers peanuts?).
- elpocko 2y agoHN's guidelines say "don't shit on other people's work". That guideline is heavily enforced sometimes, but goes out of the window at other times. It seems AI related stuff tends to be more on the "go ahead and take a dump" side of things.
- nicbou 2y agoThis user asked a fair question in a polite way
- ctrlw 2y agoCongrats, they do look good at first glance, without the usual overly shiny look, and the pure Nature images do look real to me. I'd really like to visit some of these places. However, details are still off, e.g. * the guy you linked to apparently sits in a car, but the ceiling looks like a house (at least I've never seen a vehicle like that). Reversed issue with this guy: https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/EeJBCnNsZG1IkFwTYCK5t.jpg https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/EeJBCnNsZG1... * the bicycle guy sits in the air, and the bike is mutated in several places: https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/WrfWYZlthe244Vbms8f_8.jpg https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/WrfWYZlthe2... * The face in Yoga in the field is distorted: https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/BUcURAtyzjbFd9kDm37I8.jpg https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/BUcURAtyzjb... * Hands are ok-ish but not yet solved: https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/SeO8u2HZ-V25zrHoU5nKu.jpg https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/SeO8u2HZ-V2... * Any text is obviously fake, which also affects urban environments. Agree with this caption: https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/oc6eI5w2kQQkN6pgoUSiK.jpg https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/oc6eI5w2kQQ... Bonus points for this portrait where the tower seems to have a face as well: https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/6ho0FIV-i2tWaLRo0r2jL.jpg https://d1l4k1vcf8ijbs.cloudfront.net/fakeimages/6ho0FIV-i2t...

- Carrok 2y agoStill pretty easy to spot on some of these at least. The dog in a park, the collar is obviously off. The cyclist on a dirt trail, the bike is completely whackadoo. Anything with small, specific details. Of course, in a few years (months?), models will get better at this, and even those tells will fade away.
- mhink 2y ago> The dog in a park, the collar is obviously off. Interesting note: my wife works with dogs, and I just took that photo over and asked her what breed she thought it was. Her first take was "it really just looks like an old mutt, I can't tell the marking colors. Maybe some Rottweiler in there?" When I pointed out the collar she took a closer look, and then pointed out "oh, and look at its legs! They're way too short for its body!" Which, in retrospect, is the most hilarious error in the picture, hah.
- typeofhuman 2y agoIn the near future, will be even want to share real photos and videos? Why actually travel when you can easily generate photos and videos of yourself doing all sorts of things in all sorts of places? I can't even tell what's real and what's AI. I'm actually more likely to assume an authentic image is AI!
- Difwif 2y ago> Why actually travel when you can easily generate photos and videos of yourself doing all sorts of things in all sorts of places? This is such a depressing but accurate take on travel. At least if it's true I can finally enjoy everything without the crowds of selfie sticks.
- klyrs 2y agoI spend an inordinate amount of time looking at plants and pictures of plants and the first image I was shown prominently displays a species very familiar to me. Only, it's subtly wrong, with weirdness along the edges. It jumped straight of the page and distracted me from the rest of the image. Oh well, real life sucks anyway
- smrtinsert 2y agoEven as a big supporter of image gen ai, I don't like realistic "photos". I remember hitting photorealism and proudly showing them to my wife and she goes "awesome, where is this?" Something about the fact that these were completely fake and not real absolutely sunk the value of them for me. It's a fraud - there's no history in the image, no true cultural value. It's not a capture of a place or emotion, it's a mimic. The architecture not real, the people never existed, the animals incorrectly visualized, the light doesn't behave as real light would etc etc. I think the sweet spot currently is in obviously fake stylized images or illustration/3dish type stuff. I know artists reject that, but I think it will eventually become a paintbrush of sorts for them, not replacing them anymore than code gen ai replaces software engineers. Another angle on it - I think there's something really wrong consuming fake images of real life but thinking they're real. It's like the visual equivalent of artificial cancer causing sweetener. I would want to know if the blog image I'm looking at is ai generated or not.
- rvschuilenburg 2y agoThere's also this LoRa for Flux that generates "1999 Digital Camera Style" images. Those are also very realistic in my opinion. It's probably due to the imperfections and how mundane the photo's are, that make them believable. https://civitai.com/models/724495?modelVersionId=810420 https://civitai.com/models/724495?modelVersionId=810420
- DougN7 2y agoWow. We have really opened Pandora’s Box. Imagine what political opponents and their supporters will be pumping out with this stuff. This makes me sad for my children’s futures.
