I took my pictures at my school in the 200s of my school. I took a picture of the stairway. My photo shows a lot of vertical lines and some horizontal lines from the hand rail, brick wall and the window. I was at looking at the railing about 2 feet from it. I was trying to focus on the whole staircase. My photo is both horizontal and vertical. I followed the rule of thirds, the railing lines up with the bottom post.
