Regarding post #82
In the 1980s the US photo magazine Modern Photography published at least one article showing 35mm SLR photos of the same scene shot from the same camera position through three different lenses: normal, wide angle, and telephoto.Yes, distance to subject sets up the angular relationships to the camera.
So, if the distance to the subject is the same, say 6', and the subject is printed the same size in separate prints, then both prints should have the same perspective.
The print sizes would be radically different if un-cropped.
The normal and wide angle shots were then cropped so that the same areas at the same size were printed side by side in each shot. The only differences were in apparent grain due to the differences in magnification to make the selected areas of the normal and wide angle shots the same size as the telephoto shot. There was no difference in the apparent perspective. It was a convincing demonstration of the fact that scene perspective is controlled by lens-to-subject (or eye-to-subject) distance and no other factor.
