Yes - most pro location-photographers are familiar with the "Hail-Mary"
camera position... (a super-wide lens helps...;-).

Possibly....;-)

There are three that I am familiar with: the waist-level finder (some
top-end cameras have removeable finders, allowing you to view straight
down [or up, if inverted overhead] into the camera [the WL finder is
just a set of folding leaves to cut out stray light, with a flip-up
magnifier for focus]) - OK for H, but not V orientations of the
camera (image is backwards for H, but upside-down for V...;-); the
right-angle finder attachment (fits on the SLR eyepiece to allow
down or up viewing with the camera V or H, but your eye must be close
to it to see the image); the "sports/action" finder (allows several
inches of eye-relief [much more, if not viewing the whole screen
at once], so focus and framing can be done with the camera away from
your eye [this is very useful when shooting bugs, since the camera
can be moved toward the small subject even when the photographer
cannot be close enough to view with normal finders]).
Hope This Helps
