Stable Diffusion Public Release

Simple: a "real" photo is one in which a light field from the real world impinges on a photosensitive media (CCD, film), and directly encodes that information, with some allowance for global light levels, gain, ISO, and speed. Anything else is a modification therein. HDR, multi-exposure compositing, etc, aren't truly "real". They may be 99% real, but aren't 100% real. If you crop it, it's 99.9% real (we have models which can detect cropping and even from which region it originated, obviously it can't reconstruct the missing data).

Yes, by that definition, most photographs already aren't real.

What if I use no digital manipulation at all, but play around with focal lengths or perspective to produce the desired effect. Is that a real photo?

For example from covid reporting: https://twitter.com/baekdal/status/1254460167812415489

Sure, I'd say that's a real photo - you could easily pull it off with a single exposure of film.

Just because the photo is real, doesn't mean it's free from deception. I could take a "real video" of gorilla suit^W^W bigfoot and it'd still be deceptive.

So if I take a photo of a photoshopped photo, it is a real photo.

It is a real photo of a photoshopped photo, not a real photo of the photoshopped photo’s subject.
