(...) dist. from camera = (fisheye const.)*(actual height)/(photo height) + (small obscure camera dependent constant) Since you only ask about the relative distance, the "small doesn't matter. (...)

I guess I'm imagining the same actual image in and out of focus and not seeing actual change in the image's shapes & relative sizes... (...) (23 years ago, 14-Aug-01, to lugnet.off-topic.geek)

I think I have to open a camera (or an optics textbook) and have a look. (...) (23 years ago, 14-Aug-01, to lugnet.off-topic.geek)
