Evidence that auto levels loses details --
take a photograph (or a scanned engraving, or whatever) and open
Levels, and press autl.  Note that the little triangles marking
the end-points are not under the ends of the black part - in
other words there are multiple pixel values that are used in the
image that end up having the same value after "levels".  I'll
attach a screenshot that shows the triangle isn't at the end of
all the values, but some way in.  This behaviour is good in some
cases and not others.
