I wonder how this compares to similar initiatives by e.g. Sony [0] and Leica [1]. [0]: https://authenticity.sony.net/camera/en-us/ [1]: https://petapixel.com/2023/10/26/leica-m11-p-review-as-authe...

I knew that Leica is generally expensive, but the model on the review is insanely expensive (over 10K USD?). It is not even comparable.

If you take this to ILM's The Volume, you can prove that The Mandolorian is real.

This looks like a hipster toy.

It’s possible that this could have value in journalism or law enforcement.

Just make it look the part. Make it black and put some decent lens on it.

I’m not seeing what this is product is trying to solve? A zero knowledge proof to say it isn’t AI ? I think you could do this with a disposable camera or Polaroids and a photo scanner that makes the zero knowledge proofs .

What proof is there that the photo scanner is scanning a genuine photo and not something AI generated that looks like a Polaroid?

I have been happily using fujifilm x100 for about 10 years now? I bought a second hand one for about $300. You can buy a decent camera cheaper than a smartphone, as it should be.

I love my medium format film cameras. I think everyone interested in photography should try it. Yashicas (just as an example of a company that made good medium format film cameras) are surprisingly affordable on eBay. I've had good luck buying from Japan, FWIW.

I'll throw Mamiya 645 in there for a good medium format camera as well. Yashica is great, I own a Yashica Electro 35 and it is awesome no thought rangefinder.

Could Apple or Google do this without updating their hardware? I see a relevant patent (US20220294640A1) and it looks like one of the inventors is at Google now.

Seems like it.

> a photo scanner that makes the zero knowledge proofs

Presumably at some point the intention is to add other sensors to the camera e.g. for depth information.

back in my day when we wanted to prove a picture was "real" (and not Photoshopped), we just posted the .NEF file

I'm pretty sure forensic cameras already exist for this purpose. And as far as I can tell, there isn't really any bulletproof way to do this other than embed a signing key in the camera and hope no one manages to extract it, rendering the whole thing pointless.

I guess you could have a unique signing key per camera and blacklist known leaked keys.
