Where There's a Shadow of Smoke There's...a Shadow of a Chimney

I liked these pictures that I took several days ago. I felt they were full of opposites: frost and sunshine; the frost implying it was cold enough to need indoor heating and the shadow of what was coming out of the chimney implying the heating was on inside the house; and the idea of the intangible - the shadow - representing the tangible - the chimney and rooftop.
