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.
Ignore that - it's worse!!
