Double Rainbow on Evia, Greece

March 22, 2021

Double Rainbow 2021-01-04

Photographer: Dimitris Malliaris
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).
