The following hillshading was created with the hillshade tool (spatial analyst) in ArcMap 10. Its DEM is from SRTM (1 arc-sec, about 26m resolution). It covers 18km on the ground. No image improvements done.

When I calculate hillshade from the same underlying DEM in Landserf (http://www.landserf.org) with applied vertical exaggeration = 1 and aspect bias 50 (from 0 to 100), and with the same light direction, then it looks like the following: This one is better, less rugged and the features appear clearer. Also the aspect bias of 50 gives stronger contrasts.

How can I implement such a hillshading method from Landserf in ArcMap so that it yields a similar result? Exist somewhere useful Toolbox-scripts? (For example I have found the Swiss Hillshade model from from ESRI Mapping Center). And especially, how can I implement an aspect bias function?
I'm very thankful for any hints and suggestions.
