I found this photo particularly beautiful because of the intersecting lines of the straight trees and the rays of sunshine.








These cattails are basically a collage of lines, and I think the mix of colors and the contrasting brightness makes them stand out even more.



The rows in this supermarket create interesting diagonal lines, highlighted by the repetitive shapes of the food items.




This row of turtles is a softer, more natural line, but it still creates a path that the eye is drawn to follow.



The carefree branched lines of the tree, the geometric lines of the spiderweb, and the indistinct lines in the background allow this image to radiate from its central point in a subtle way.
