Photos – lunar halo, water strider, and a septuple rainbow

Water Strider

Water Strider

Those dark spots sitting underneath this water strider aren’t exactly shadows 다운로드. They’re patches of darkness created from distorted light as the little insect walks on the water’s surface.

Septuple Rainbow
