To be precise, the 'perspective' (relationship of main subject to its surroundings) was altered by changing the camera position for each shot, the 'subject framing' was kept constant in all the photos by changing the camera position to suit the FL being used for each shot.

I see that my Sticky colleague SkipD has already brought this up. Nice illustration of this principle, OP...we're here to fix the terminology used :D! I've been trying to convince him to coauthor another Sticky, on the topic of DOF and the many variables behind this, out-of-focus background blur amount and the variables behind this, and 'bokeh' quality...THREE different but related concepts.

can somebody please do this on a face instead of a car? will be helpful in understanding the effect of lenses on portraits

OMG an actual FL comparison keeping the subject the same size!

Amazing!

Kewl!

We should fire-up a sticky ONLY of this type of work.

I thought it was pretty cool myself, thank you. And great idea.

I was just looking for that :) A very good illustration.

Wilt, please do this! It is the topic I am most unfamiliar with and I'm sure I am not the only one! :)
