Vertical

"So show me the line you require." Black Country, New Road
A film photo that we took on the cliffs of Dover. The lighthouse, the pipes, and the standing human people are creating some nice vertical lines -- dividing the photo into sections and making the image feel taller.
Horizontal

"Sanctuary" - Arca (feat. Ryuichi Sakamoto)
From a film I shot over the summer. The pews in this chapel create several horizontal lines as well as the table in the background and the banister on the ceiling. The particular use of these overlapping lines gives the image a bit more of a deep feel.
Diagonal

"Skyline to" - Frank Ocean
These trees were just grown in the most beautiful way. Three lean right while one leans far left. These lines do divide the frame up into thirds, while having the largest tree and the dirt that it is on cut through all of them.
These are each so epic! There's so much depth in that second one and I think a lot of that is due to the different lines at play in each plane of the image. I also like how the lines in the foreground of the third one are the most prominent, but the ones in the background across the stream also catch my attention and follow in the same pattern.
