What about drone selfies? That's definitely a term, and it breaks your criteria. Could we call this a timed tripod selfie?

I propose that photographer must a) be the primary subject of the photo, b) be engaged with the camera in some way, in order to categorize as a selfie.

So yeah, pretty sure this isn't a selfie. Also this makes me want to play the new Metro.

Well, he did put himself in the photo, which wasn't at all necessary for documentation. And doing so arguably increased his radiation exposure. So I think that "selfie" fits.

It does not. The amount of risk involved is not a factor. The term "selfie" refers to the inherent narcissism of the focus of the shot.

In a traditional selfie, when you move, your arm moves with you and your self remains the center focus of the shot. A drone selfie acts in a similar way. A timed shot on the other hand will always capture a specific scene, whether you are in it or not.

Arguably Eschers lithograph "Hand with Reflecting Sphere" does qualify, but Korneyevs picture doesn't.
