In blackest night, from the parking lot, in the wet and dripping fog, I looked at the silhouetted trees. There was street lighting behind the trees which glowed through, appparently creating an orange cast. However, I saw the scene in black and white.
I intentionally underexposed the image to make the outlines of the trees appear stronger. Exposure data: 56mm, 52 seconds at f/4.8 and ISO 100, tripod mounted.
