Can a picture be "ORTHO" without definition of the viewing environment?

Recall my suggestion about the "exercise" of walking-around-a-room in 
front of a projected image and seeing how "distortion" varies
significantly (more in some images than others) as one moves
around the room.  It really "works".  I've done it (club did too
a few weeks later).

My personal experience is very different from this.  Looking at a 2D 
photo of a distant view, or looking out of an airplane window at all
the "small" houses, my brain interprets the situation as "big things
far away".  When I look at a hyper image view of the same, my
brain interprets "small versions of usually big things at some 
distance".  VERY VERY different to my brain's way of processing 
things.  


Other brains may vary.... :-)
