Using lines in composition is next. The course manual says that there are two important things to bear in mind. The eye follows a line (real line) and that it also tries construct a line from appropriate suggestions (implied line). The more active the line the stronger is the encouragement of the eye to follow it, and diagonals and curves work better than verticals and horizontals. The most common visual clues to follow a line are a row of points, the extension of a line, or lines that seem to point in a direction, the extension of visible movement such as a car, and finally the direction in which someone in the picture is looking (eye-line). The exercise required us to find implied lines and to take two photographs. Firstly, an implied lines where the eye is led firstly by an eye-line. Secondly, by an extension of a line. The results are below. In the first photograph the barman's gaze leads us to the drink he is measuring. In the second photograph the explicit line of the fencing leads us to the character.
