Summary Authors: Dimitris Malliaris; Jim Foster

This amazing double rainbow formed over Evia Island, Greece, following a strong storm, just before sunset on January 4, 2021. The image is a composition of 9 photos -– the camera is facing east, opposite of where the Sun was setting. In order for a double bow to be seen, the drops must be large enough (several mm in diameter) to accommodate more than a single reflection. Rays that emerge after the second reflection make up the outer, fainter bow. Note that the prominent darkened strip of sky between the primary and secondary bows is called Alexander’s Dark Band. Raindrops along the sight lines between the two bows are unable to scatter light toward your eyes, and thus this area is much darker than areas that lie on the outside of the bows.

Photo Details: Canon EOS 6D camera; Canon 24-105mm f/4 L IS USM lens; 24mm focal length; ƒ/5 aperture; 1/80 sec. exposure time; ISO:100; Adobe Photoshop CC (Windows).
