The photo above shows a classic 22 degree solar halo over the 80 ft (25 m) Kravica waterfall in Bosnia and Herzegovina. It was captured during a road trip I took in the Balkans, from Dubrovnik to Mostar. I noticed the cirrus clouds and then turned toward the Sun and was very pleased to see this halo. Randomly oriented ice crystals composing cirrus clouds refract sunlight to form halos, generally with subdued colors, approximately 22 degrees from the Sun -- a little more than two-fists held at arm's length. Always use caution when looking in the direction of the Sun. Photo taken on May 28, 2018.

Photo Details: Canon 600D camera; Vivitar 8mm fisheye lens; F7.1; ISO 100; 1/2500 sec. exposure; Post-processing in Adobe Camera RAW 9.5.1 and Photoshop CS6.
