black and white

In this picture I used Lines, as an element of art, because you see the white borders of the stop sign, which is an octagon.The borders are in contrast with the dark, normally red color, of the sign and the dark forest in the background. As a principle of design I used Emphasis, because, the stop sign is in the foreground and in the centre of the picture. The black and white filter creates adds drama to a ordinary street sign.
