A long exposure can make for an excellent photo. By keeping the shutter open for a few seconds, a photographer is able to pick up a wider range of lighting than in a fraction of a second shot. It can also give some great lighting effects, like the starbursts from the very bright street lights and spotlights. JasonianPhotography certainly shows us what kind of lighting is around National Harbor and the Awakening statue, does it to great effect.
And, of course, the photo helps us get into the Christmas spirit!
