When you're 20 miles up, no recon photo is *sideways*.

The oblique camera angles shot from a Blackbird were a lot more "sideways"
than the Keyhole photos taken from geosynchronous orbit.

Very few satellite shots are right at nadir either. We have special code in our software
to compute the "up" angle that the squints like to have their images rotated.

Keyhole is not in geosynchronous orbit. They are in (undisclosed) polar elliptical orbits.
