Sundogs and a solar halo around the Sun, December 19, 2013, shot from home with the Canon 60Da and 10-22mm lens. The halo is caused by ice crystals in the air, in this case very nearby as they can be seen as “stars” sparkling in the sunlight in the sky and in the foreground. This is an HDR stack of three exposures at 2/3rds stop intervals, processed thru Photomatix Pro.
