Macro or Micro? Scientists' pictures baffle our sense of scale

It began when Stephen Young, a geography professor at Salem State University in Massachusetts, tricked his biologist colleague Paul Kelly into thinking a satellite image was one of his electron microscope scans. The two then began collecting and creating images that baffle our sense of scale. The images, which include close-ups of a dragonfly wing and aerial pictures of the Sahara desert, have now been exhibited at both Salem State University’s Winfisky Gallery and Clark University’s Traina Center for the Visual and Performing Arts. Can you guess whether they are close-up or very far away?
