Earlier quoted context omitted.

You may be confusing display-referred and scene-referred image data. 1. Clipping occurs in the scene-referred raw camera sensor pixel data at capture time. 2. Raw processing software fills in the highlight by supplying the missing colour information. Often this happens by default. 3. When you obtain a display-referred JPEG, the missing information for clipped highlights was already supplied. Tone curves and other adj…

What are you talking about? I see clipped histograms come out of cameras all the time. I’ve been working with digital images and digital photo manipulation for thirty years. Regardless, it’s not generative AI making up details. The differentiated pixels are there in the camera jpeg even if traditional image processing techniques have to be used to make them visible onscreen. The complete structure of the feathers tha…

Subject domain knowledge mismatch appears to be too strong for further constructive discussion.

So HN, any theories on how this happened ?

Seems like they used some AI tool to remove speckles from an image. The tool has to generate a likely replacement. And one of the speckles looked a bit like a coin.

Your explanation could make sense for TFA, but definitely not in the case below

Maybe cryptobros with zero skills and no talent created too much images copy-pasting the same bitcoin image over everything, which caused poisoning of training data.

I also expect some bug involved, where user selects a circular mask, but outer edge is slightly blurred (feathered), which, when multiplied with white background, gives a light circle-shaped contour. After that Photoshop fills not a "hole in the sky", but a "light circle-shaped object" in the sky.

Sorry, tangent, but does anyone remember the AI zoom in some old phone camera that was hallucinating a celebrity's face? It was much before the moon zoom hallucinations.

Ok I'm getting tired of this habit of deep linking to apps. The apps either override existing web pages featuring the same content, or there's a web redirect to an app I might have installed but am not signed into. So in multiple cases, it's difficult to just read whatever the information is. Web pages are universally accessible. Everyone has a browser on their device of choice. The web is 35 years old. Access to inf…

I don’t know why you’re getting dogpiled over this, it’s a terrible experience of creeping non-consensual computation. I had the official bsky app installed, but I ended up with Graysky at some point and just forgot about it, and somewhere along the way my browser vendor (Apple) and the app vendor (bsky) decided that I would probably tolerate this horseshit. Reddit pulls the same shit but that’s extra special because…

> non consensual computation

Gonna steal this one.

I have to say that I think the photo without the Ligthroom processing actually looks better. The second one hasn't just added a bitcoin, it has also added the "AI shimmer" that seems to be a part of a lot of generated images. I can't put my finger on exactly what the characteristic is, but my first instinct (separate from the bitcoin, which was hard to find) is "that's an AI picture." Someone should just spend some t…

That could be the VAE? The "latent" part of latent diffusion models is surprisingly lossy. And however much the image is getting inpainted, the entire thing gets encoded and decoded. Edit: I'll note some new models (SD3 and Flux) have a wider latent dim and seem to suffer from this problem less. AI generated images are also biased strongly towards medium lightness. The photographer's adjusting of the tone curve may s…

You absolutely do not need to encode and decode the whole image, even in ComfyUI. All you need to do is composite the changed areas back in the original photo. There are nodes for that and I’m sure that’s what Adobe does as well, if they even encode in the first place. These tools don’t really work quite like inpainting. There’s no denoise value - it’s all or nothing.

I’ve used Photoshop’s generative fill many times on singular images and there’s no loss on the ungenerated parts.

If you zoom in and squint your eyes, it does look like some kind of shiny coin. What I'd like to know though... is how is the model so bad that when you tell it to "remove this artifact" ... instead of it looking at the surroundings and painting over with some DoF-ed out ocean... it slaps an even more distinct artifact in there? Makes no sense.

I mean, this is notable because it screwed up. It usually does a pretty good job. Usually.

In this case there are better tools for the job anyways. Generative fill shines when it’s over something that’d be hard to paint back in - out of focus water isn’t that.
