Low-level track view
is another low-cost mount that places the lens a full inch lower to the
track than the hi-level mount. This seemingly small distance
yields a surprisingly more realistic camera view as if the view was
standing on the ground right next to the subject.
one problem with this mount is that because the angle tends to be more
upward than the hi-level mount you are more likely to shoot the ceiling
unless you are closer to a backdrop. Note that while the mount
is designed to align the camera with the tracks for head-on shots it
does not have to be used that way. You can rest it on the ground
perpendicular to the tracks for broadside photos of an engine.
Few notes on construction. When you build this kind of mount make sure
you have room between the camera and mirror mount when the lens are
extended. Also, note that the mirror is hinged to adjust the
framing of the picture.
