As I said, I can believe that you feel that in 3D as a brain, yes, hallucination or fake 3D, extracted from other information ( I think is not difficult for any in this forum to realize your brain works in a extrange way ).
As you said shade/fog can contribute to depth perception, unless in space there is no fog but in nebulas, so that shade, if is there, is not related to depth.
But, even if I can asume the possibility that you feel 3d sensation looking a 2d photo where is no depth information available ( like fog or perspective ), I can´t in any way think that the depth information you think you are extracting from that photo is representative of reality, because that information simply is not there.
If you agree with this, nice. If you don´t there is extremely easy to prove you wrong. You can render two spheres with arbitrary different sizes, one closer to the camera and then you have to tell what one is closer. There is no way you can do that without pure casuality. Or even more easy. You can do this even in the real world. Pick two stars at night, guess wich one is closer, then compare it with astronomical data. You will found you wrong most of the times.
