The brief for this exercise was similar to the previous to go out and shoot images which suggest diagonals. The course notes suggested diagonals were rather easier to create in an image as they depend mainly on the view point. Straight edges such as flat top roofs to buildings or tops of walls will become diagonal in the picture if photographed along them toward the distance (perspective).
A couple of these photographs I have kept in colour as I think they work much better. I don't think the colour distracts from the suggested lines.

This jet suspended from the ceiling is a rare example of an actual diagonal as the camera was level whilst shooting. I think the tail shows diagonal well too.

This shot of some shadows has both real diagonals and implied. It was interesting to see how a zoom lens could change the appearance of these diagonals by changing the focal length.

Using telephoto zoomed in on part of a building creates this diagonal.

This sundial has diagonals running both toward the bottom left and right of frame suggesting movement.
Diagonals have a much greater sense of movement and direction as you can see from the above images. This is due to the immediate contrast with the frame edges but also because they have an implied association of being physically unstable (they don't naturally exist very much). Diagonals can add a sense of activity to an image and specifically catch the eye and take it along their length (image 2).
