Micro or macro? This one’s macro: Cumulus clouds over the South Pacific Ocean (Image created by Jacques Descloitres, MODIS Land Rapid Response Team, NASA/GSFC, additional image processing by Stephen Young.)
If you love the concept of scale as much as the next geographer, you should check out this Smithsonian website. It contains images collected at the macro scale by a geographer (using remote sensing) and at the micro scale by a herpetologist (using a microscope). Can you guess which are the macro images and which are the micro?
