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.
