Looks to me as if it *was* taken from the F-16 in formation with AF-1. Canopy glare is showing (right above and in front of the 28000, and the out of focus top of the cockpit at the bottom of the picture, gives some idea of the "downlook" angle.

That conclusion makes me really wonder about the "photo op" nature of the mission. If you were doing a real photo shoot, you'd lay on a "chase"/photo aircraft that was equiped for air to air photography, without such artifacts.

With a "professional" photo outfit/plane, you'd get something more like this:

That's the same aircraft, 28000.
