Chris,
The images you have are "raw" images. That is, there is no calibration
block. So, using the default color enhancement table make things
look like they are inverted.
I attatched an inverted lut table to this message that you can place in
$GEMTBL/luts (called invgray.tbl).
To add this table to the list of gempak enhancements in nsat and nmap,
add this invgray name to $NAWIPS/tables/nsat/enhance.tbl and
$GEMTBL/luts/enhance.tbl. For garp, add to $GARPHOME/tables/sat_enhance.tbl.
