It's just an optical illusion. Rotate the PDF 90 deg to the right,
and it looks "right". I usually choose azimuth=315 for
r.shaded.relief. When the sun is from the NW, shadows appear
"below" the features, and we visualize mountains as raised and
valleys as lower.<br>

Ooops, Correction: when azimuth=315 the sun is from the *South*
West, producing naturally looking relief maps.<br>
