Reading Aerial Photographs: The Southerner's Advantage

Abstract : Aerial photographs of the most mountainous areas of the Northern Hemisphere are subject to a concavity/convexity reversal illusion, due to three facts: that sunlight comes from the South, that the visual system is bound to interpret concavities and convexities as if light always came from above, and that North coincides with above in the pictures. This fact is particularly damaging now that aerial photographs are ubiquitous. A remediation is proposed.
