approx 60 - 80mm FOV 35mm equivalent... or not particularly wide

for both shots, same focal length; one taken closer to the ground, the other at eye-level

usually, if conditions permit,

a relatively non-wide shot will exhibit all shadows diverge by very little in the FOV if they were cast using a single source, like the sun

whereas a relatively wider shot will exhibit all shadows diverge a great deal, almost in nearly opposite directions all within the same FOV if they were cast using a single source, like the sun.

and so all shadows cast using such single light source (like the sun) will diverge out with angles in inverse proportion to length of focal length.

the longer the focal length, the less divergence.
the shorter the focal length, the greater divergence.

it's quite simple, and straightforward by just visual inspection alone (if one could compare two different focal lengths, it would be even more obvious)[distortions notwithstanding; or corrected for or fringes cropped out].

even though i've not specifically measured the differences, but when one has no 'different' focal lengths used, for a give set scene, one cannot tell for a subject that doesn't have large or clearcut shadows. harder if one is very close in to the subject, like the top image, or if the scene is relatively feature in the center if farther off the ground like in the second image.
