[gdal-dev] Converting from 16 bit to 8 bit images (best practices?)

[Jonathan Greenberg]

Folks:

I am using a piece of software which is relying on an older version of GDAL
that doesn't have the "fix" to deal with > 8 bit geotiffs (it is trying to
make a jpeg overlay but can't from a 16 bit image.  I think this is the
issue: http://trac.osgeo.org/gdal/wiki/TIFF12BitJPEG), but when I do a
straight convert (-ot Byte) the output image looks really washed out.  Any
hints for getting the best quality output from a 16 bit to to an 8 bit
conversion of a Geotiff?
