Levels to pull the ends of the histogram out and adjust the midpoint if
needed - - - and there you are, all the efforts,
successes and failures of lens design for contrast are washed away. Add
LCE and Curves and you'd never know it wasn't
taken with a nicely contrasty lens.
Um, no. just expanding the histogram to change the contrast does not
magically recreate the information lost to a low-contrast lens. If only it
were that easy. A lens with good contrast will always capture more
information than a low-contrast lens. If artificially modifying contrast
was enough, everyone would have been designing low-contrast lenses back in
the day and just using high contrast materials with them (film, paper).
Such is not the case, obviously.
