Crater Adivar on Venus
The 30km-wide crater Adivar on Venus, imaged in synthetic aperture radar by NASA's Magellan (1989–1994). To make this version I inverted the b/w radar image, used noise reduction and colored it to a "Venus" palette (based on Venera images.) See original at t.co/vZYCBEudjm?amp=1
Radar images aren't like optical images, they aren't in any particular color wavelength for one, and they determine the smoothness (dark) or roughness (bright) of surface textures more than the way optical light reflects off them. I felt inversion (reversal) showed shape better.
