[gdal-dev] Hillshade + Topographic Map??

I have managed to create a hillshade using gdaldem and I have my original
topographic rasters. However I do not want the standard grey hillshad or
apply a colour ramp.

Is there a way to combine the hillshade and topo map together - ie add a
transparency or opacity to the hillshade.

I have looked at Photopshop and ImageMagik but the results are then not
supported in QGIS etc

After a trawl through the web the only entry is an ArGIS 10 tutorial


Hopefully that will explain what I would like to achieve

thanks for anyones help
