The sky was still overcast, and so without the flash, the only available light was from occasional street lamps along the path, and their reflection off of the snow. The amber lights cast a subtle golden hue over their surroundings which appear more intense to the camera's eye. The low lighting and absence of tripod also explains the hazy images and mottled appearance.
The night was quiet. The snow-laden branches muffled most of the sounds, including that of an excited Jack Russel Terrier straining on his leash to relocate familiar smells, now disguised by the snowfall. You can see a fuzzy Benny at the bottom of the photo if you click to enlarge it.
The dock is one of two spots where we'll typically feed bread to the ducks. Benny, on the bottom right, knows he'll luck out and get a few clumsily dropped pieces. You'd think it was steak the way he gobbles them up.
