I went out to photograph horizontal and vertical lines and, as suggested in the brief, to try to subordinate the content of the photograph to the line.
These were steps in a medieval building. The horizontal lines are quite strong, though the fact that thet are steps can possibly be seen quite easily.
Possibly not quite so obvious, these are overhead electricity cables photographed against a blue sky.
This is an image of a wooden fence – again perhaps slightly easier to discern than the cables.
Perhaps more difficult to work out – this is a picture of the trunk of a Silver Birch tree with the, papery, bark peeled away. I was intrigued by the horizontal lines in the tree and the banding produced by the bark being peeled off at different time.
On to vertical lines
This is a close up of a pillar (in the same building as the stairs above) the ridges forming detailed vertical lines.
Here the mooring poles show strong vertical lines, although maybe in this case the picture is not so strongly subordinated to the lines as in others.
This is a, cropped, photograph of the canopy of a market stall. The vertical lines are very strong (although becoming slightly diagonal from the edges).
This final image is of a vertical wooden post, the green colour is from aging and the vertical lines formed from fine cracks in the wood.
What did I learn from this exercise? I enjoyed this exercise it was fun going out to look for lines in a photo and I was quite surprised at the number that I found. It was particularly interesting to try to make the subject image subordinate to the lines – it showed me that you can find images within images.
