 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).
