This is not caused by looking at NW hillshades, but by looking at real life objects where light normally comes from above. This is what your brain is expecting and therefore it generates a 3D "bump map" for you that way.
And that's why a GIS uses a sun position from the top of the map, often north.
(Turning your SW map upside down should fix the problem.) Raymond _______________________________________________ QGIS-User mailing list QGIS-User@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
