High-quality heightmaps in Photoshop

[Javen]

Thanks for that link. It is an interesting idea I'll have to try out tomorrow when I am working. It will definitely solve the problem of trying to take my already-made topological maps and adapting them to work with a political one.

One thing I have trouble understanding is why it appears the DEMs on that site are reversed. The Rockies are presented as the lowest point. I think, though, with http://www.shadedrelief.com/natural3/pages/extra.html, I should be good.

Thanks for all your help, waldronate.

Is there a standard convention for either white or black being the highest? I think i've seen i both ways.
