Hello. I have a DEM and want to generate hill-shading. I have heard you can use photoshop however I am not sure what to do with the DEM to start with. I have access to MapInfo GIS software, and the Engage 3D add-on - plus photoshop.

The articles linked below from Tom Paterson's www.shadedrelief.com site should have what your looking for. If you run into trouble with the PhotoShop method let me know, I may be able to do a rendering for you in Natural Scene Designer.

Yes, you can generate hillshading / shaded relief image from DEM image with Photoshop. You might want to download our Geographic Imager. If you do not have Geographic Imager yet, please download and install the evaluation version of Geographic Imager. You can import dem datasets to Adobe photoshop. In the Geographic Imager tutorial dataset, there is a javascript to generate a shaded-relief. If you do not want to generate the shaded relief with the javascript, you might want to contact Avenza Support (support@avenza.com). I will be happy to give you the instruction on how to do it manually step by step.

I hope this helps :)

Cheers,
Kimi

David and Kimi's suggestions are both good. What software are you using now to view your DEM? You should be able to export it as a tiff, which is readable by Photoshop. Then you can use Tom Patterson's excellent methodologies.
