In the cold weather the emissions from a smoke stack really shows up more. A lot of it is steam and appears in the minus temperatures, like car exhaust. I approached this stack from the north just after mid day.
The sun was back lighting the smoke and making it look very dramatic. The coolness of the image along with the building at the base enhanced the “industrial” feeling to the picture.
As I moved around the location, changing shooting angles, the back lighting turned more towards side lighting. This brought out more color in the stack itself, while retaining a bit of the back lighting on the smoke. It also allowed the colors appear warmer in the smoke and the stack itself. The tighter framing lets you see the curls of smoke forming as it exits the top of the stack.
In the best light…
