In this exercise I had to go out and photograph different objects and scenes that were made up of Horizontal and Vertical lines without repeating each type of image.
A flight of steps illustrate horizontal lines perfectly.
Perhaps the most obvious horizontal line ... Horizon.
I choose a bridge in distance to add detail.
Line of shoes laid out horizontally.
The slates on this roof accentuate the horizontal lines.
The tall reeds here extend nicely from the bottom of the frame upwards, giving the appearance of vertical lines.
From this angle the vertical lines of the steel gantry sign and ladder towering above the nearby trees helps illustrate this point.
Vertical display case of sunglasses
The trees planted in row helps highlight their standing position and trucks (vertical) while the tracks in the rapeseed field disappear in the distance, giving another set of vertical lines.
