Lights seem to be the heart of decorating for the celebration of Christmas and New Year’s. Light is to a photographer as oils are to a painter. The strokes of the brush on this photograph were defined by the choice of the shutter speed giving the picture a life of its own. Experimenting with light can yield many results, including some that come as a pleasant surprise.
