Nikon D7000, Nikon DX format sensor size (i.e. APS-C format). The
|
||||||
|
EXIF data claims there was a 50mm prime lens (>>DATA<<) attached.
|
||||||
|
HOWEVER, because we're not at infinity focus, the close focus effect
|
||||||
|
approximately halves the field of view. Otherwise I can't get the
|
||||||
|
unproject perspective to work out correctly from the photos for the
|
||||||
|
foam blocks. That calculates to a horizontal field of view of 14
|
||||||
|
degrees, and using the box dimensions to scale the proportions, the
|
||||||
|
lens aperture was about 5 feet from the ground, which means that you
|
||||||
|
must be about 6 feet tall standing up straight. That all sounds like
|
||||||
|
sane values.
