The purpose of this exercise is to study both horizontal and vertical lines as they appear in an image. These can be lines formed by a solid structure or shadow or even by objects creating implied lines in an image. According to the course notes the most successful example of a line within an image is one that draws the viewers eye.
In the image above the stone wall creates a solid horizontal line which is reinforced by the people sitting side be side along it's length. There are other elements within the frame which enhance the horizontal line. From left to right there are points of interest which hold your gaze.
These start with the service box with the can on top on the left. Your eye then moves along to the man's outstretched arm, along the 3 people to the bag and cups which continue, filling the gaps, and extend the line to the right hand edge of the frame. Although horizontal and vertical lines are considered to be less active than diagonal lines or curves, this image provides a pathway for the viewer to follow and is probably less static than some other examples.
Unlike the first image the horizontal lines in this image only partially fill the frame. However, the clear, uncluttered background ensures that this is the most prominent element in the image.
This image is an example of an implied line. Although the flag poles themselves are vertical and could have been used as an example of vertical lines, I don't think the vertical is the most obvious element in this image. The horizontal line that is created by connecting the row of flags is much more prominent.
There are several potential points of interest in this image although there is also a strong horizontal element in the stairs.
Vertical lines formed by 2 standing figures.
A strong vertical line created by groynes at Aberdeen beach. Although there is also an element of horizontal lines the vertical is far more prominent and leads the eye into the frame. This line has a strong sense of direction from the bottom of the frame to the top.
Again in this image there are both vertical and horizontal lines. The vertical line of the fence is more prominent due to it's lighter colour.
This image of a telephone box is another example of a vertical line which dominates but only partly occupies the frame.
