Hi, I can confirm that question is in GDAL which by default considers four band images as RGBA which is also documented in http://www.gdal.org/frmt_gtiff.html The following gdal_merge command gives a good result when source bands are in four separate tiff files and it is possible to select bands 1-2-3 for natural colour or 4-2-1 for false colour infrared in QGIS. gdal_merge.py -separate -of GTiff -co photometric=rgb -co compress=jpeg -o fourband_rgb_jpeg.tif 1.tif 2.tif 3.tif 4.tif -Jukka Rahkonen- _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
