One of the ‘benefits’ of cold weather in Alaska is when the the lights ‘polarize’ or have the ‘halo phenomenon’. The ice crystals in the air create a sort of light saber. It’s neat when it’s just a few white lights, but when you get lots of lights of various colors, then it’s absolutely beautiful! The best place I’ve found to see this is at the airport. All those blue, red and green lights that are evenly spaced apart can create an amazing effect.
Keep in mind that this was taken with a digital camera in regular light mode. The higher iso ratings make it quite grainy. These are best taken with a film camera with an extended shutter speed.
