Andy,
You started me thinking of a fantastic project . . . To make a Mercator Projection of a human face, with all the different possible midpoints.
Greenland looks huge on a Mercator Projection when the center of the map is on the equator. . .how big would the ears became if the projection were centered on the nose? Or how big the nose if the center were the ear!
Wow,

. . . from the pov of the lens the info beyond the “spherical horizon” is invisible and would limit the extent to which a correction could be made. . . .

Darkroom work behind the scenes so to speak. Problem? Maybe. I saw something that indicated computers were able to make portraits of people that did not exist. Interesting … what will they think of next.

Many portraits are made with the camera too close to the face and noses appear larger that from a normal viewing distance (in life) and ears too small. Has the perspective of photographs been tackled by AI people?

Over weeks of taking photos with the device, I realized that the camera had crossed a threshold between photograph and fauxtograph. I wasn’t so much “taking pictures” as the phone was synthesizing them.
