The standard needs a bit more baking before it's quite ready IMO

I wonder if we can create a small device that sits on the camera hot shoe with a crappy camera that takes a “verified photo” every time you press the shutter button. You use the main camera photo primarily but if anyone cares to verify you can look at the embedded verified version to see it’s largely the same.

Yeah, there are plenty of modern cameras that don't have it, but it would still be nice for Sigma to join the other camera manufacturers that are supporting C2PA.

Hell it doesn't even have IBIS. I suppose they have to cut corners somewhere for the size constraint.

there's no threat model for this (mass-media image authenticity verification) that attestation solves. i mean, i know people will say that there is, but they're all wrong haha.
