 			<p>The <b>nadir</b> is
 the point directly below the person viewing or below the camera (set a <a href="Pitch.html" title="Pitch">Pitch</a> of -90 degrees in PanoTools). The opposite (above) point is named <a href="Zenith.html" title="Zenith">Zenith</a> and has a <a href="Pitch.html" title="Pitch">Pitch</a> value of (+)90 degrees. The horizon or equator is in-between and has a Pitch of 0 degrees.
-</p><p>The Nadir is streched to a line in <a href="Equirectangular_Projection.html" title="Equirectangular Projection">Equirectangular Projection</a>, making it hard to edit directly. However, a <a href="Rectilinear_Projection.html" title="Rectilinear Projection">rectilinear</a> view can be extracted for editing. 
-</p><p>The Nadir usually gives much more problems than the Zenith because there either is a tripod to cover or there are <a href="Parallax.html" title="Parallax">Parallax</a> errors to edit. Objects at the nadir tend to be much closer to the lens and therefore errors in the setup will more likely be detectable in this part of the picture. One possible way to solve this problem is to use tripod caps.
