 From JohnPW's other comments, it looks as if I may want to do something
other than ImageMagick's sigmoidal mapping on the two extreme synthetic 
brackets.

convert o1.tif -brightness-contrast +10  -sigmoidal-contrast 5x0%  c000.tif
convert o1.tif  -sigmoidal-contrast 5x25%  c025.tif
convert o1.tif  -sigmoidal-contrast 5x50%  c050.tif
convert o1.tif  -sigmoidal-contrast 5x75%  c075.tif
convert o1.tif -brightness-contrast -10  -sigmoidal-contrast 5x100%  c100.tif
enfuse --output=o2.tif  c000.tif c025.tif c050.tif c075.tif c100.tif

So - when stretching (emphasising...) the highlights I also knock the down a 
bit,
and (conversely) when doing the shadow I bring them up a bit.

The mid ranges were already handled nicely by the sigmoid.
