The shadows across this image taken by the European Space Agency (ESA) Copernicus Sentinel-2A satellite image may play tricks on the human eye, making the valleys—the green areas—look like they stand higher than the light blue mountains. Sometimes rotating the image so the shadows fall in a different direction can “fix” this optical illusion.
